I don't mean to come across rude but why do you give a dam, there are thousands of these idiots on the road, leave them be, let them get on with their dodgy driving standards, if they are willing to take stupid risks, the best place you can be is as far away from them as possible, to reduce the risk of having your car damaged.
I have 4 vehicles that I drive on a regular basis & it's amazing how your treated on the road.
-In the zed I get people wanting to race me & few people give way
-In my Leon I blend in & get little bother other than from the boy racers in their other vag variants
-In my van nobody messes & people generally give way
-In my dads Audi I get little bother as people think I'm a generic Audi driver, obviously you get the generic BMW drivers acting like Audi drivers
At the end of the day there are so many things in life to get upset/annoyed or worried about, some prat in a focus should be at the bottom of your list.
