I was driving on the highway today and I was notified of an upcoming exit 1 KM away. This is far too short of a notice and I had to cut about 3 lanes in half a kilometer to be able to make the exit. All other GPS devices give a notice 3 KM in advance as well as the 1 KM notice. This is a critical suggestion which should not take much dev work to implement but will have a big impact.
