Never give in
Walking through London in the morning you see many cyclists jumping crossing lights or trying to run you over on a zebra crossing. If it's early enough (no witnesses) and they could easily have avoided you/stopped and they are very close, then they generally get a good thump and at least an abrupt unscheduled dismount.
The really unlucky ones don't try to cycle off afterwards... :-)
