I wouldn't mind to give my feedback, but I'm one of those people who prefer to use in-car dash, and even our current ones have almost everything that I need. The only external HUD element that I need is a radar. Maybe sometimes standings to check out who's where, and then turn it off again.
I'd give it 8/10 for appearance based on the colours, layout, tidiness of the graphics. Is the tyre info just tyre life, or does it have temps too,
