Drivers and pedestrians are expected to follow the road rules they learned in school but in reality, that is often not the case. Pedestrians cross against a red light if the road is clear. Drivers lose patience in slow traffic and cut into the next lane when they see an opening.

Experts say that technical limitation will slow the widespread adoption of autonomous driving in urban and city environments.
