Wow. Let's be the stereo typical m3 owner and be elitist to a car that's half the price and assume every action is an attack on your ego.
Ever consider maybe the nod, rev, or look might just be their way of saying hi or showing appreciation? Or maybe even if they wanted to race they're just trying to see how well they'd do against a m3 and nothing else?
This is probably why some never feel like they experienced it and some feel 'attacked' everyday.
