You can't use your smart phone while driving. People tend to use their smart phones anyway which has caused a big increase in distracted driving and the resultant carnage. What's the world coming to when some schmuck on public transit can do things like play games or even get work done where a driver can not do that? What's worse is that smart phones make public transit a lot more usable and attractive in general. Self driving cars keep the automotive transportation mode more competitive.
