Down to 30cm - good! Now all we need is a GPS-enabled app for urban pedestrians that reminds them to look left or right just before they step off a curb into

Down to 30cm - good! Now all we need is a GPS-enabled app for urban pedestrians that reminds them to look left or right just before they step off a curb into oncoming traffic.

As a runner I’d appreciate the corresponding app to remind drivers to look both ways before turning right.

  I sometimes think DMV should require a coordination, or some kind of computer driving simulation test. I don't think a quick spin around the block weeds out the people who shouldn't be driving. If you fail more than three times; you don't get a driver's license. Or, need to wait a few years, and reapply.

  It's always the right turners who just stare left and then go...

or a running app that creates a route as you're running, so say you want to stop for a car so you turn an keep running in the new direction it could recalculate immediately and get you to one of your waypoints more quickly.

Actually, I was part of a team that built a GPS based walking navigation system for the blind (Google Microsoft Cities Unlocked). The limits of 5m accuracy were an incredible danger that prevented us from doing any u assisted trials. Even highly trained and skilled cane users would wander into the roadway usually within 10-15 minutes of using the system, purely because of GPS drift. And forget about ever using it in urban centers. In London, Boston and NYC it was rare to be more accurate than 50-100m. It's scary how bad GPS accuracy really is.

  Road navigation apps only work as well as they do because they lock your position to the road and assume no excessive changes in velocity.
