I was just thinking about this today (and have been for a while now), but with regards to vehicle comfort.
I drive a small sedan, but have ridden in pickup trucks and SUVs. They are far more comfortable than the sedans the way they sit taller, have far more room, and feel like a small bubble protecting one from the rest of the world.
This is a danger on two fronts: safety, and comfort leading to more driving. If we continue to make cars more comfortable, we continue to abstract the idea that we are zipping around in 3,000 pound death machines, thus leading to more reckless or risky behavior.
As autonomous vehicles roll out to the public, no doubt people will expect computers, internet, and television to be front and center. Others may take naps during commutes. But with this, rather than curing the disease that is longer and longer commutes due to policy that encourages sprawl, entertainment will just treat the symptoms.
