Even then, even if you can solve every case involving actual roads with perfect markings and intact signs and functioning signals, I’ve found myself just this week:

- driving across an unmarked grassy mound to park a car at a store in their designated area.

- paying a fee with coins to enter and exit a toll road.

- stopping to move around roadworks based solely on hand signals from one of the workers.

These aren’t even scratching the surface in terms of edge cases that could be encountered regularly.
