That won't work for all the people who'll suffer car sickness when they spend time focusing on their phone while in a vehicle. Intermittent messaging is OK for most people but have you tried reading a book as a passenger? We might find that most people have to look out the windows so often that they can't get much productive work done.
I used to have car sickness as a kid. I recall some of it being caused by vibrations made by the engine. The smell of gasoline was also vomit-inducing for me. Both of those issues are solved by electric cars.
