Rubbish - this will cause an accident before long. If I put a destination in and choose a longer route it continually tries to put me on the faster route until it is no longer faster and I have to interact with my phone every time to cancel it. Surely you should make the interaction for the faster route as this would only be a one time press and not half a dozen because I am passing another roundabout. Any faster route when I have chosen a particular route should only be due to incidents
