Re: Yes, it IS a game of chicken.
"When they start to do that in front of me and I have the right of way, I look right at them and keep the power on."
Are you sure you have the right of way? Weren't they there before you? Are you at or below the speed limit? Are they supposed to second guess that you will step on it when you see them? (A-hole alert! Run kids, run!) Heard of this thing called "common courtesy"?
You just illustrate all that's wrong with drivers' attitudes in the UK. The worse you get, the sooner laws will come that will put you in your place. (Or prison, in some cases.) Same as parking all over pavements, etc.
