I now have a big car... so I enjoy being able to set the speed limiter to 20mph and know that there's no chance a car is going to be able to squeeze by me. Also, there's something about driving a Volvo, people just seem to accept you're going to be driving like an old person.
Regularly get people beeping and flashing lights in frustration behind me when I'm driving through 20mph zones at 20mph.
