Cellphone safety

My concern is the use of cell phones while driving.  I know this may be an unpopular idea but it may be one that will save lives.  Would it be possible to develope some form of technology that would prevent a car from starting if an activated cell phone is inside of a vehicle?  This is just a random thought that I considered passing along. Thank you.

They need to make it so you can dial hands free. That is my hugest gripe with hands free is that if you don't have someone's number and you want to dial a directory or you know someone's number but you know it isn't in your phone, there is no way to do it hands free unless you do something illegal like pull out your phone on the interstate and look at it and then dial in your number. Sure it will probably connect to the hands free still but that is not legal.
