Beeping at cars on m25 for leaving a safety gap in stop start traffic. Riding peoples bumpers and continuously beeping along with swearing at drivers as passing. No matter how much of a hurry this is not acceptable driving.
Parked illegally on hatched lines with zero consideration for the elderly, disabled, children or those with prams/kids and anyone else that just wants to cross the street safely.
Never mind what would happen if an ambulance/fire engine had to get by in an emergency!
Loves cutting corners off junctions into the other vehicles right of way.
