I've lived in many cities, both large and small and do see driving differences to areas. Drivers generally account for the area traffic conditions.
I live in Las Vegas now. Many visitors causing erratic patterns as their driving varies. Las Vegas area traffic managers accounted for it by devoted turn lanes and signal arrows and extending the signal times in red/yellow/green. A lot of people running red lights, so drivers slow to move on green change. A lot of pedestrians hit for many reasons.
The SoCal area is high density and heavy traffic gets people on edge. Many change lanes a lot and cut in at exits. Tailgating common. When traffic is light, many roads have a lot of lanes and people drive fast. You get some driving very slow and some speeding. It makes awareness very critical. Many people do not watch what is going on around them until passing an incident and rubbernecking, backing up traffic for miles even when no lanes are closed.
In Detroit I find high speeds and tailgating.
In Austin Texas I found hugging the right lane on a multi-lane road.
In Arizona, speed limits are ignored.
In Boston and Philadelphia, one way streets, sometimes random instead of alternating.
Drivers compared to where?
Rural versus urban drivers are very different when out of their standard domain.
