But then again most things is safer in the US because there is generally 3 times as much space on any given street.

That's not true; by most comparisons, the US does worse in road safety than most European countries, certainly worse than the UK (although there are of course some considerable variations within the US). Just the fact that there's more space doesn't necessarily make it safer; it can cause people to have less awareness of risk.

However, while I've been meaning to catch up on it, I'm not aware of the current data that one might compare between London and NYC. That would be an interesting one. I'm sure someone's done it somewhere.
