I'm not talking about one-ways, those are confusing in general. I'm talking about clearly marked off-ramps from freeways. In one situation the person had to drive over a fairly large bump in the median just to enter the wrong side of the freeway; again many signs to prevent such a thing and they still ended up in that predicament. Sometimes miles down the freeway before a cop pulls them over. It's terrifying.

I saw another one where the car tried to turn right into an off-ramp with a line of cars waiting at the light. Like wtf, do you not see the wall of cars and headlights in front of you? Where are you going?!
