This is not how Android Auto or the equivalent iPhone app works. The phone reroutes as it is needed, a car screen is used to display the navigation stats and instructions, but everything is continuously controlled by your phone.
I don't really see why a bike GPS approach would be different, perhaps the bike industry lags behind the car's by a decade.
Anyway, you are right, the standalone rerouting on Komoot is not the best. I commute in a rural area that is frequently getting flooded or they close roads for roadworks. Google maps work way better that Komoot, but even Google tends to reroute me to that 60mph narrow and twisted road that has a non-stop display of fresh flowers and police tapes on both sides of that road.
