The cars you mentioned are probably people THINKING they are faster than your BMW - I have shown quite a few they are wrong, even in my 3.0i.

The other thing I noticed is that they might not be as close as you think they are. I had a car one day that would not get off my arse. Finally stopped at a red light and swore they were touching me, so I got out and looked. They were further away than I thought they were. SO it may just be perception on your part.
