Having grown up in Melbourne AUS and now living in Hong Kong (both cities with trams), I have to say that it is not too hard to avoid the tracks if you have your brain in gear.

Sure, I've had at least one good accident involving a 700x23 tyre and a tram track (you just slot right in!), but it ain't rocket science to learn how to jink the front wheel so that it crosses at a big enough angle not to cause a crash.

Learn. Deal.
