Good. He knows the law, no point moaning if you get caught. Same with speeding etc, take the risk at your own peril.
Not saying that he was moaning, of course
On your other points;
1. Not quite, it's just the CARB certification that's the issue. There's ways and means around it, especially if you live close to the state border.
2. Plenty enough for 99% of the time, if you're into trackdays then you'd have it removed for £20.
3. I didn't know that, really? Even though overtaking is allowed both sides? Crazy.
4. So do we :wink:
I prefer to compare ourselves to the Aussies. They've got it really tough, with huge restrictions on stuff like lowering the car and very very tight speed limits where even a brush over can put you in trouble. I certainly wouldn't want to live there as a petrolhead.
