I would love to specify how open i am to re-routing before a journey - i.e. being able to choose ‘reroute automatically - get me there ASAP’ or ‘don’t reroute without confirmation - prefer my route where possible.’

Why: I drive a specific one of two ways out of my city when taking a long journey because while the other road is technically faster if you drive at the speed limit it is also dangerous and has poor surface conditions. This means in reality it is slower and stressful. If I do not manage to cancel the re-routing in time, I then have to either try to select an alternative route on my CarPlay (not advisable driving at 60mph on winding country roads), or stop the car to reinstate what I told it before I set off.
