Last year we got a rental car when we were in Florida. When we first left the airport, we were using the navigation app that was in the car. First red light? Navigation app suddenly goes black and a commercial starts playing. My wife and I both look at each other like, "WTF is going on?!?" Light turns green commercial clips out and the navigation app starts working again. We waited to see if it happened at the next light. Sure enough, the last commercial finished and another started as the light turned green.

Tuned it off and used our phones from there to the hotel. That was the last time we used a rental cars navigation.

So yeah, its already happening.
