I think there's too much going on in that HUD for the average driver to parse. I'm also unconvinced by the choice of elevation perspective for the route guidance - even though the display is above the road, it feels less confusing to have a "birds-eye" perspective on the route guidance. As the Sheppey pile-up demonstrates, there's a lot of people who simply suck at driving - specifically maintaining sufficient braking distance and NOT cutting into someone else's braking distance when changing lanes (in poor conditions that space is for ME to stop in, not for YOU to slide into). As it is, I'm conscious that I need to be aware of the car behind as well as the car in front. The only way it'll work is if the car brakes for you, and then everyone has to have that technology.
