Allowing someone out from a road, and they dont acknowledge you or put their hand up to thank you is one.
Driving up your elbow is another, so i slow right down to wind 'em up even more, as it's you that's in front, so you have the upper hand on the fool behind....he/she can kiss my harris.
People pulling out on you without even the slightest bit of thought that you're there and if you dont brake, you crash
People chatting and looking at their passenger more than actually driving safely and properly and looking ahead......oh and driving at 20 mph in a 30/40 mile an hour zone.
If it was up to me, i would do a "Kenny Everett's mad General........"I'd round 'em, put 'em in a field.................and bomb the ba r stewards!!!!!!!"
