Jokes aside, just because we can't directly copy from other maps doesn't mean we can't use them to figure this stuff out, but unfortunately I still don't know of a source of such data :(

Someone somewhere has probably done something with a google mash up, and I know UPS in the US gives that sort of data out to emergency services to reduce trip times. When they started doing this sort of thing they saved so many tens of millions of dollars on fuel, than again in the US you can turn right on red lights except if otherwise signed.
