One behaves differently when driving, and be mindful of 360 degrees, checking the mirrors every 5-10 seconds, etc. But if one has a wall of screens, perhaps in the long run they may be able to convert the 2d (wall of monitors) to the 3d (360/surroundings) and sense it accordingly.
Lag/downtime/tunnels/etc. would kill, and should be flawless.
There is absolutely no way someone not at the risk of their life could pay attention well enough to drive for more than a few minutes.
