One of the biggest bugbears I've had with using Google Maps is the - not entirely illogical - assumption that you go everywhere by car. Its a real disadvantage when you look at getting directions off the thing when you want to go by foot, and has been the one clear advantage that whereis.com.au has (aside from the fact that I think whereis is marginally more accurate). For this reason alone, I've been reluctant to use Google Maps as a primary resource for map directions.
Well, Google look to finally have gotten around to this, with the addition of getting walking directions. This is especially handy in cities where you get a lot of one way streets that make no difference if you're on foot. This - combined with the ability to customise and personalise multiple maps and locations, probably gives GM the edge now. It’s just creepy that they know where I live!
