This. When doing a bunch of errands, that involve lots of stopping and getting out of the car, then getting back in, it seems to take a good minute for Android Auto to re-load every time I start the engine. Must be even more annoying for delivery drivers. This is on a 2-year old car. I don't even think it's Android Auto that's slowing it down, but the head unit's OS is taking that long to boot before it will allow Android Auto to start. Surely the whole thing could be kept switched on (in sleep mode perhaps) for 30 minutes after the car is stopeed?
