Android Auto would love to see
Speed camera icon like you have on the Amigo app (so can report camera or say its removed)
In the banner for arrival time and distance, have it displaying the delays as you would if just using a mobile phone screen.
You could even put in there the distance to next services, petrol station
Most of these are on the phone screen and would be great if tomtom can implement them on android auto or get google to authorise these features
