I know we all like to bitch and moan about how cars aren't simple, stripped-out, super light machines we can all fix in our own garages with a starter set of tools. I do it too. But a lot of new car technology is actually pretty useful, and successful in making them safer and more efficient.

But sometimes new tech work as well as we want, and there's always room to grow. That's our question of the day: What technology isn't on cars, but should be?

Besides better smartphone integration like , which I'm excited about because they probably beat the hell out of most infotainment systems, I'd like to see automakers do more with HUDs and projection. Wouldn't it be nice if we could swipe through holographic menus like Tony Stark does in his workshop? Then you wouldn't have to take your eyes off the road to do stuff. That would be kinda nice.

Your turn, what tech isn't ready for prime time (or doesn't exist yet) but should be?
