I got a lot of that when I owned my Megane DCi. Poeple racing me and tailing me...just idiots.
I dont spend so much time on the motorway however, there are people that, I guess, do drive a lot for a living, commute up and down motorways, who probably have young families- and seem to drive like they're invincible...if their families could see them.... typically they're in Audi's. And I do not generalise. I kid you not.
In traffic controlled motorway stretches it seems they're are a lot of people in a hurry when im doing the speed limit.
PS My 182 gets whipped by anything turbo diesel. I had a V6TDI Touareg tailing me the other day, i casually passed him on my way to work and then he speeded up as we approached a sharp bend on a dual carriageway, up hill, and sat on my bumper! I tried to hurry up out of his way but he just tailed me, i was actually quite scared as if i came off the road he'd have crushed me.
PPS Best way to rid a bumper tailer, is indicate, slow a biut then cancel your signal, then repeat.
