My theory about drivers of Mercs, Audis and BMWs is that a great deal of them are r soles. I judge this by their road manners. They tend to be utterly selfish, stopping in the middle of the road, parking badly, including parking in a disabled space without a blue badge, etc....
If you call them out, there are two stock responses: "F off!" or in the case of inconsiderate parking "I was/ will be only 5 mins".
I am not saying that all of them are tuuats, before drivers of those cars on this forum complain!
