Yeah, now you mention it I'm not too fond of going to London by any other means either, but driving is definitely the worst way to do it by some distance...

(Not, I hasten to reassure any Londoners reading this who I like, that there aren't things and people that make a trip to London worthwhile. It'd just be even better from my point of view if I could experience those things and see those people without having to go to London to do it :-)
