Overall my understanding would be that People should be able to use cell phones while driving, not many people would say it's safe but when it comes down to being responsible, I think people like that, that know how to manage their time on the phone and as cautious as could be , with a Bluetooth speaker in their car would be good source to use instead of having to pick up the phone and having to put it up to your ear in making it notice , but if you are as responsible as people who know how not to pick up a phone you should try using Bluetooth in your car for you can start using it.
