Hey it "just works" in Firefox on my PC too
Good job with rules they look like you can build a car relatively cheap. And the motor claim rule is a big stick to wave at people who want to spend to win.
I am not a huge fan of the no antifreeze rule this means a lot of coolant draining and refilling for those that want a multi purpose car or live anywhere it gets below 32 degrees. Is this a common road racing rule?
