A Tech Fix for Texting While Driving

By now, almost everybody with a cellphone and a car knows that it's a bad idea to text while you're driving.  But people still do it, and some of those people die in text-related car crashes and take innocent victims with them.  What if technology existed that simply prevented people from texting from a moving car at all?  Wouldn't that solve the problem?

Scott Tibbetts thought so.  Tibbets and his company Katasi were profiled in a recent New York Times article for developing a promising technology that would simply block texting from any phone that was in a moving car.  While there are several technological solutions to this problem that are already on the market, they all have various problems. 

Some text-blocking apps work by using the phone's GPS to figure out if the phone is moving faster than walking speed.  If it is, the software concludes that you're driving, and blocks texts.  This one turns out to be a battery hog, because the GPS system has to run all the time.  It also might present problems for train and bus passengers.  Another system uses the car's speed sensor and links it to the phone with a Bluetooth wireless connection.  But it costs over a hundred bucks, and there aren't that many people who are both concerned enough about texting while driving to buy it, and also willing to shell out that much money for something they could do for free with a little more willpower, perhaps. 

Mr. Tibbetts' solution is cleverer than these.  It involves connecting a wireless box to the car's OBD-II port—the on-board diagnostics socket that the auto technicians use to figure out what the "service engine" light means.  When the car's moving fast enough to be dangerous, the wireless box sends that information to the cellphone network, which then asks the phone—once—where it is.  Then, if the network is using the software developed by Mr. Tibbetts' firm Katasi, the software uses the location data to figure out things like who is driving the car.  You don't want a whole family's text service blocked just because Mom is driving to the grocery store, for instance.  That way, the GPS battery-drain problem is minimized, and the computational heavy lifting is done in the cloud, so to speak, rather than by the phone.

Mr. Tibbetts, an aerospace engineer and entrepreneur, has persuaded both an insurance company and a cellphone provider (Sprint) to cooperate in test trials, which have worked fine.  But it appears that the largest player, Sprint, has gotten cold feet lately, and has stalled further tests.  In the Times interview, Wayne Ward, vice-president for business and product development at Sprint, expressed concerns about product liability.  Currently, if a driver texts while driving and gets in a wreck, it's the driver's fault.  Mr. Ward asks what might happen if Sprint sells the Katasi system that claims to prevent such accidents, and then some glitch happens and somebody sneaks through a text and crashes anyway?  Why, Sprint could be sued!

Pardon me, but it appears that there's more going on here than meets the eye.  Any time a small independent company comes up to a big firm and offers the big guy new technology, the not-invented-here problem can raise its ugly head.  Short of buying the small upstart outright (which happens a lot, by the way), if the big firm adapts the small company's technology, they will be on the hook for royalty payments or other forms of obligation that big companies don't want to be tied down to.  And there's also the simple pride factor expressed by the phrase "not invented here"—if we didn't think of it first, it can't be that good. 

Besides, it's not clear who would make enough money to offset the expenses of the added hardware and software—and lawyers' fees, if Mr. Ward's fears turned out to be correct.  The existing GPS-based solutions for text blocking in cars aren't exactly selling like hotcakes, even after all but five states have adopted no-texting-while-driving laws of one form or another. 

One could imagine a legal solution:  make something like the Katasi text-blocking system mandatory by government fiat.  Nobody has seriously put forward that idea yet.  But it might happen.  There was a time when ordinary window glass was used in automobiles, with the result that otherwise minor wrecks turned deadly when razor-sharp knives of glass flew around and sliced—well, enough said.  But when the technology of laminating glass with a plastic inner layer was developed around 1920 to keep the shattered pieces together, auto companies adopted it, partly motivated by fear of lawsuits.  Eventually, most countries made it a legal requirement for all glass in automobiles to be laminated or safety glass, but it looks like the firms were ahead of the government in that case.

Safety glass is a different kind of thing than automatic text-blocking.  An auto company could start using safety glass and just raise the car's price incrementally, and hardly any customers would notice the change.  But as soon as you stop a person from doing something that they're used to doing, like texting while driving, you create a sharp negative impression.  And that's something that cellphone providers are reluctant to do as long as there are competitors ready to take business away.

My hat is off to Mr. Tibbetts, who put five years and millions of dollars into developing a clever technological fix for a significant problem.  But as many engineers turned entrepreneurs have learned, building the better mousetrap­—or text trap—is only part of the problem.  Convincing people to buy it and use it is often harder than coming up with the invention itself.  If everybody used something like the Katasi system on their cellphones, we would all be safer, no question about that.  We would also lose a little freedom of judgment which we can now exercise, which is whether to text while driving.  Perhaps some telecomm industry leaders will get together and agree to adopt Katasi, or something like it, but such inter-company cooperation for a non-financial thing like safety is a rarity.  It could happen, though.  I bet Mr. Tibbetts, for one, hopes that it will.

AT&T Considers Data-Only Billing

What if you had to buy gasoline for your car in the same the way you have to buy cell-phone service nowadays?

First, you’d have to pick a gas company.  You’d go in, fill out a form or answer a bunch of questions, and then you’d have to sign an agreement to stick with that gas company for a year, say, or else pay a $200 broken-contract fee.  Once you agreed to that condition, you’d have to pick your gas plan.  Do you want gas just locally, or for long driving trips?  Gas for a sports car, a pickup, a minivan, or a lawn mower?  Want extra quarts of oil every 2,000 miles?  You have to make all these choices in advance, and then you’ll get billed a fixed fee, more or less, every month, at least as long as you don’t use more than your maximum number of gallons—plus eight or ten dollars’ worth of taxes, air-pollution recovery charges, and other government nitnoise that nobody but the lawyers can figure out.  If you go beyond your plan’s maximum amount of gas, though, you’ll end up paying big, maybe six bucks a gallon, for every gallon you go over.  And by the way, you have to buy your car from the gas company too—it won’t run on gas from any other company.

Sound pretty silly?  Yet if you substitute “phone company” for “gas company” it’s a fairly accurate description of how cell phone and related wireless-network services are sold today.

In the interests of full disclosure, I am no longer a fan of AT&T.  My childhood regard for that firm bordered on adulation, bolstered by their support of the legendary Bell Laboratories and reinforced by a positive experience in high school with an Explorer Scout group run by a bunch of telephone engineers.  I stuck with AT&T through the Ma Bell breakup in the 1970s, but parted ways with the firm after going on an extended trip in the summer of 2000 and committing the unforgivable sin of using my cell phone to call home a lot.  Because of this sin, I paid through the nose, several hundred dollars at least, and switched to Sprint as fast as I could after I got home.

Now that AT&T has more or less reassembled itself out of the sundry pieces that the courts chopped it into, its clout in the market makes it worthwhile to pay attention when its CEO, Randall Stephenson, speculates about future pricing structures.  On June 1, Stephenson said that “in the next 24 months” we may see phone companies selling phone, data, text, and other services on a “data-only” basis.  While he wasn’t too specific about the technical details, this probably means something like charges based on the number of bits transferred, rather than on other arbitrary things like number of text messages sent or number of minutes talked.

The arcane and ridiculous way that companies currently charge for phone and wireless services came about through a combination of historical circumstances, marketing ploys, and government regulation.  Back when there was nothing but POTS (plain old telephone service, on landlines), the big expense to the phone companies was their long-distance networks, once they had installed local plant and equipment.  So the custom of a flat rate for local calls plus per-connection fees for long distance arose, and at the time it made sense.

Then came multiple revolutions in telecommunications technology:  fiber-optic cables and digital transmission (which vastly lowered the unit cost of long-distance calls) and wireless, which increased the volume of data sent and added new varieties such as text and images to the mix.

Technically speaking, it is more challenging to carry the data representing a two-way phone conversation than it is a one-way text message.  The allowable network delay can’t be more than a fraction of a second, and there are difficulties with sidetone (hearing your own voice), echoes, and other things that increase the cost compared to simply sending some bits from one point to another.  Yet my current cell phone plan lets me talk as much as I like locally, but charges me 20 cents for every text message I send, even if it’s simply “OK.”  If you send “OK” via ASCII, a seven-bit-per-character code, that’s a total of 14 bits, or more than a penny a bit.  If I paid that much for a typical phone call, it would run into thousands of dollars.

A sensible billing system from a technical point of view would charge nearly nothing for actions that use nearly no bits, namely, things like texting and email.  Two-way voice would come next, then still pictures, then movies.  The network companies have to structure their pricing so that customers use enough bandwidth to keep them in business, but not so much that their network bottlenecks (e. g. cell-phone tower equipment) gets clogged and spoils the party for everybody.

As things stand, I suspect it’s kind of like a cartel.  Everybody is getting away with the inverted structure of charging more for texts (which use few bits) than for phone calls (which use more and are inconvenient network-wise).  But as soon as some upstart outfit gets out there with a data-only billing plan, the whole house of cards collapses and the consumer wins, in my view.  My guess is that the AT&T head’s announcement is a way of telling the market that they are prepared for the deluge if it comes, though how they are going to deal with it is not yet clear.

All the same, I look forward to the day when cell-phone pricing is a little more rational.  I don’t think it will ever be as simple as filling your gas tank, but the way things stand now, it’s like medical-insurance billing and tax forms:  it takes an expert to catch another expert who’s cheating, and the average citizen doesn’t stand a chance against a company that decides to bend the rules, or to create Byzantine price structures that are legal but so complex nobody can really know if they are getting a good deal or not.  Let’s hope Mr. Stephenson’s prophecy comes true, and maybe I’ll even consider going back to AT&T.
