In Google Maps, there is a blurb that pops up every so often, telling me that Google Maps has found a faster route while I'm on that route. If there is a slowdown or a crash that closes the road, have Gemini reroute me. I get if I miss a turn, I get rerouted anyhow but if there is a crash or something else, a little A.I. would be more helpful than guessing where I need to turn or having the app tell me to turn onto a road that isn't as choice as the road I was on.
