I was going to go with my general mutant response about teleporting! I could cut in lines, go to every QC meet, wait tables so much more efficiently, enter high security vaults, leave high-security prisons... but then I realised that I really, really like driving and giving that up would be kind of crummy.
I'll have to think about this one.
However, Tommy, I do have a suggestion for yours! Instead of having the petrol come out of your mouth, it should come out of your butt. It would be much less messy, and instead of spending hours of your day vomiting and not being able to get anything else done, you could just sit on a toilet-style receptacle and do a crossword or get those blowjobs. You'd have to have some sort of seal around the bowl though so the Parisian ladies would not pass out from fumes.
