You can usually spot the type of driver on the road to be wary of:-
1. Anybody wearing a hat. Its either an old codger, or a chavster in a baseball hat (yes, I know I'm wearing a hat, avoid me obviously

)
2.smashed up old bangers for obvious reasons.
3.BMW/AUDI drivers. Have to overtake everything on the road, have right of way everywhere and not to indicate Also they have to make up for their small manhood's somehow...
