Just some older guys in a golf gti (180bhp I think) who spotted me at the petrol station with my mate (who is also the same age)....they started making comments about the car and and asked how long i'd had it etc. Then I heard one of them say to the other 'its probably his dads car' as they got back into there car...which annoyed me. When we both pulled back out onto the main road, they started driving quite aggressively and cut me up at the next set of traffic lights (which annoyed me even more!)...up to this point, I didnt really want to give the car any, because a Z4 3.0 vs a Golf GTi, would have been quite embarrasing. However, unfortunately I let the testoterone filled male side of my brain take over and booted it passed them (smiling at them as I went pass) to create a bit of distance (which I did, quite rapidly). However, a bit further down this dual carriage (by which time the Golf had caught up), I needed to come off, so I indicated to go left but this guy wasnt having it (he was trying to match my speed to stop me from coming into the left lane). I sped up to try and shake him, but I didnt want to go too fast as I was running out of road before the junction. So I had no choice but to brake, very hard and go across the hatchings at the junction. The car behind me came about an inch from my bumper, not to mention I nearly hit the golf crossing over to the junction. Maybe if I hadnt shot of pass these two guys earlier, they wouldnt have been so persistant on stopping me from changing lanes.
