I think the problem will be when large volumes of cars get directed into quite neighborhood streets more designed for local traffic, not thru traffic. Kids out playing hockey or B-ball in the street, lorsof joggers and people out strolling. Suddenly it's I-5 because google defaults and says you save gas crossing these neighborhoods at 25 mph. Sadly the traffic won't go 25 mph becuase they still want the fastest route or will make whatever they are driving into the fastest route.

This is why so many new developments don't connect with the surrounding developments in a way to even allow thru traffic.
