It really is cool technology and something which can make night-time driving much more safe. I've driven the demo BMW 650 with the FLIR PathFindIR (an old product) and it's pretty fun. Since you essentially 'see' heat, lights don't blind you and you can see up to 4 times farther than with visible light. This old system was marketed to emergency personnel (police, fire, etc.).

One problem I found, was that I unconsciously started driving off the small LCD screen rather than looking through the window and glancing down at what the FLIR camera was showing - not a good idea!

IR cores have been dramatically reduced in size and cost recently, so I could easily see this being much more mass-marketed in the near future and something a DIY'er or stereo install shop could easily do.
