San Francisco's hills are a very localized issue. Most cities are pretty flat. London included.
Of course it's just a matter of time until GPS programs integrate topographical awareness, and give you the ability to avoid steep climbs.
Its also just a matter of time until cars provide visual aids for navigation, and not just the voice on a GPS device.
- pimlottc 12y agoI think you're being a bit dismissive. Hills are just one example - every city has its local issues, be they hills, rivers, different laws, traffic patterns...
- mikeash 12y agoRivers are irrelevant to a GPS. Rivers only matter to a car to the extent that they determine the road layout, and GPSs know the road layout. They're also pretty good about laws, although there is still some trickiness about things like left-turn prohibitions that are only in effect at certain times. It's getting better all the time, though. Their traffic data is in my experience better than human estimation at this point, since they can route based on actual current conditions rather than extrapolations from past experience.
