Suppose that there is a GasBuddy user who is driving down a street, and the GPD signal is lost at time t $=0.$ Also suppose that the average speed of traffic is $2$ mph$.$ The error in GPS localization is $20$ m $(0\mathrm{.}012$ miles$),$ while the error in mobile tower$-$based localization is $250$ m $(0\mathrm{.}15$ miles$).$ Consider that location information is requested by GasBuddy every minute.
