I haven't seen the movie yet, so I can't comment on exactly what the invisible car is, but for all intents and purposes, the Stealth bomber and jet fighter are invisible.

>I'm a big believer in technology, but I don't think we'll see (no pun intended) invisible machinery in our lifetime. I don't think there is a car that operates (as well) by remote control like the last BMW did either. I don't think we have auto inflate tires either. Hmm, didn't he have a watch that had a laser that could cut through armor plating in Goldeneye too? Plenty more of them gadgets that I don't think are out there yet.
