As someone who doesn't own a car anymore I was fairly shocked recently at some of the stuff that you find in current BMWs. They do have a HUD-like navigation that's a windshield layover for example. I know they do quite a bit of HCI research. I'll be curious to see how many Tesla employees will pop up at CHI next time around. I think there's some interesting research to be done automotive AR...especially if there's an automated driving component.
