The only real problem I regularly encounter is on two lane roundabouts.

If you want to take the first exit you need to enter in the passenger side lane.

If you want to take any exit after the second you need to enter in the driver’s side lane.

If you enter in the passenger side lane, you must take the first or second exit. Taking any exit after the second from the “outside” lane is gonna cause an accident.

I see this happen a few times a year. It’s so common that most drivers foresee it.
