It enraged me so much I thought I'd post it just in case the driver happens to be a forum member. Driving on the M5 today and witnessed an A3 sportback (SE trim I think), silver, VRM: MA60 NWY driving like a complete idiot! This guy gives Audi drivers a bad name and nearly caused several accidents with his tailgating and undertaking habits. I thought he was going to take me out when he swerved across two lanes, undertook two cars and then pulled across two lanes causing cars to urgently brake. He must have been doing nearly 90mph as well. Keep a watch out, near Exeter, this guy is dangerous!
