I’ve driven Car2go a couple of times this week. On both occasions, while driving through downtown Seattle, the car announced that I was outside its home area. Presumably it tem­porar­i­ly lost a signal and thereby assumed that it was no longer in the home area. Given the car knew my position and direction just moments before, and that I was well inside the home area, any half-way decent algorithm would have concluded that it was physically impossible for me to be now outside the home area, and kept its mouth shut.
