Since this is a forum that is global, we all must look at the world wide responses. What happens in the U.K. and the USA are two separate issues.
Once your gas prices hit $10 per gallon, you will find a lot more oil burners on your roads. Diesels over here are generally cleaner than petrol engines (thanks to some really clever tech) and actually have lower tax bands because of it.
Take the 6 cylinder 3.0L BMW engines. The diesel is more powerful, more economical and cleaner than the petrol.
Europe have had emmisions targets longer than the USA for road engines, marine restrictions came in in 2006, just like you.
