Was driving along, hunky dory then all of a sudden I looked in my rear-view mirror and saw an Audi TT, it was in the fast lane and I blindly ignored it, then suddenly I noticed it pulled in behind me but instead of slowing down it appeared they carried on going around 70-80Mph while I was doing a modest 55-60, anyway it appears they rode my bumper for a good 30-40 seconds then pulled back out, then I witnessed this and was bewildered at the move they made, how they could've crashed and risked everyone on the coach? Some people's logic.
