my apologies for lack of clarity, over here they are called indicators, but yes, turn signals would be the one. It is always possible that over in North America BMW drivers use their indicators - certainly in the UK they dont...maybe its just a manufacturing issue on the european models.
as for being jealous, i wonder what of? if you want to get onto a mine is quicker than yours argument or some such then fine. My mate has a bmw 325...my vehicle beats it off the line comfortably. In fact, just the other week, i had a ferrari pull up beside me at the traffic lights...a nice 460. I beat that as well. 0-60mph (100kmh) in under 4 seconds does me fine.
