    I've been waiting for this feature in an iPhone navigation app for years, but it still hasn't happened. The GPS in my Acura MDX uses this feature for tunnels and such. In order to do this, Waze can, upon losing GPS signal, start taking readings from the accelerometer and average them over a short period of time to estimate changes in speed (speeding up or slowing down) to adjust the speed where GPS signal was lost. The solution is that changes in direction would appear as +/- X values and changes in speed would appear as +/- Z values at a rate of 0.04559g for every mi/h/s change in acceleration. Here is the reference to the UIAccelerometer API regarding this:


    I think this feature would make Waze very cutting edge and show that it is a real contender in the navigation app category. I love using Waze and hope that my contribution makes it a better app for everyone.
