I have to agree with BHD here, GPS and even AGPS are highly subject to
the radio signals. Even an accelerometer based solution would fail as
the phones can change physical orientation independently from the
vehicle, so short of using the phone as a car key which in turn disables
it, your pretty much stuck with the potential text messaging while driving.
It would be much better to simply teach your kids to be good and safe drivers and not be little douche's behind the wheel. That said, its the other idiots I am more concerned with as a parent, I have control over how much training my kids get before being allowed to drive, but not the other millions of people who rely on their gym teacher to learn the rules of the road.

I am intimately familiar with this problem and solutions that attempt to solve it. There are serious issues with solutions that use the phone's GPS capabilities, however. 1. While GPS can be highly accurate for location ID, it suffers when signal strength is not strong, resulting in a false calculation of movement. This is especially heightened if the user is sitting inside a building; the phone does a location query, which places it at X; it does a second query, to determine speed, and it places it at Y. When the GPS signal is weak (or tower triangulation), then X and Y can be significantly far apart, even though the phone is on a desk. But the program doesn't know that, so it does the speed calculation and then disables the phone! 2. GPS-based systems must constantly query its location 24/7, draining thebattery in 1-2 hours.3. To avoid killing the battery that quickly, these programs will typically build in a delay - don't constantly query the GPS; instead, just do it every X minutes. BUT, that means a GPS-based system must allow low-speed use, giving temptation for use in rolling traffic, AND it'll have a built-in delay. Imagine parking and then having to wait 10 minutes before being ableto use the phone.4. GPS-based systems cannot determine if the user is just a passenger or taking public transportation. So no using your phone on the bus, train, or in the passenger seat!

(I have no connection) This company offers the ability to block texting when the vehicle is moving. It uses the GPS systemin the car to determine if the car is moving or not - when it detects movement it locks texting out. It's described at:http://www.tvkim.com/watch/284/kim-on-komand-how-to-block-texting-while-driv ing.
