An op-ed piece in the NYT argues that there are technological means to prevent people from texting while driving. One solution offered:

When a cellphone is used in a moving car, its signal must be handed off from one cell tower to the next along the route. This process tells the service provider that the phone is in motion. Cellphone towers could be engineered to not transmit while a phone is traveling. After a phone had stopped moving for a certain amount of time — three minutes, maybe — it would be able to transmit again.

Something needs to be done!
