Infiniti's unreleased 2008 EX35 has lots of fun new features like self-healing paint and automatic folding rear seats. It even has something called the Around View camera system. It basically works just like those backup cameras that started showing up a few years ago, but now you can see to the right, left and front of you as well. I'm pretty sure that I'm the only person that could actually benefit from something like this. Since my garage is so narrow that I have to pull both of my side mirrors in just to fit, which makes pulling out just a bit trickier. [AutoSpies]
(Disclaimer: My only expertise with self healing paint is that of someone who reads Popular Science ravenously but with a bad long-term memory.)
I believe the paint technology incorporates microscopic capsules of paint that, upon puncture, release their contents. This is how it "self-heals."
I think I've also heard of this sort of tech being looked into for self-healing plastics, where capsules of 2 different compounds would puncture and combine, then harden.
