Do not make eye contact with the following:

Anyone you have just 'cut up'.

Anyone you have just overtaken.

Anyone who has just resentfully pulled over so's you can pass.

Anyone. you should have your eyes on the road, silly.

Beware of older drivers. They are generally a menace. Particularly older men and older women. Older drivers of any other category are also trouble.

Watch out for the heroes and knights of the road. These are people who stop to let other drivers out of driveways and side roads. They violate all the rules whilst thinking they are doing a favour. They aren't doing any favours, they are just breaking the flow and doing what everyone isn't expecting. If you want to be a hero, go to war and save some babies. Don't be a knight in shining armor when I'm behind you. There's a certain flow to traffic life, and everyone knows what to expect. When drivers break the flow and start letting others out of side roads and being all goody goody, it messes it up for everyone. Go where you're going and get on with it!

Older drivers do not know nothin' about roundabouts!! Beware! (Give way to traffic coming from your right - remember?)
