The topic of driving education reminds me of something that scares me a bit.
Driving educatin in germany isquite thorough, compared to some other countries. You need several hours theoretical instructions with a multiple choice test at the end, but also a certain number of driving hours with a driving instructor, some of these have to be on the Autobahn, some have to be in darkness.
I have heard of several reports of driving instructors, that many students cannot properly concentrate on driving, because they can't use their mobile phones. They get fidgety and nervous. Take a break somewhere, and the first thing out is the smart phone

I dont think it would be all that difficult nowadays for a modern smart phone to detect if is being used by the driver while driving. A quick picture with both cameras to see if you are in the drivers seat, combined with info from the GPS if you are moving or not. If the phone is coupled to the car, as gets increasingly more common, that would be even easier.
