Me too. It’s infuriating and unsafe. I don’t drive often, but when I do it’s out of the city where I’m unfamiliar and need a map.
So I also stopped using Google Maps for driving.
Who at Google seriously believes that it’s good idea to 1) unpredictably change the route someone chose mid-drive, and 2) to distract them while driving with a pop up notification that must be interacted with just to maintain the route.
If I choose a route, I chose it for a reason. Don’t change it while I’m driving.
