My honest opinion…
I would like to see the lanes with cars as default. Even when I do not have dream drive pro enabled. This lets you know if cars are snaking up behind you. I’ve noticed when DD is enabled and I try and auto-change a lane… it makes the lane red and the cars red that you would otherwise run into.
Not all would like this. Therefore it would be cool if you could enable that as your default view or not.
I also do like seeing the break lights and turn singles. Not only is it just cool, perhaps you leave a signal on and your music is loud. Maybe that would not happen anyway (as you can see the left and right camera when your signal is on).
