well i mean think about it, when the delorean came back in bttf 1 from the first TT Experiment it was frozen, and cold steam was coming off of it, in bttf 2 (and at the end of bttf 1) when doc came back to get marty(was marty to begin with but had to take jenn cuz she saw the del) the delorean had only a little bit of steam on it (of course now that i think about it in the same film when doc and marty went back to 1955 and landed behind the billboard the del was frozen...hmm anyways) and in bttf 3 when marty went back to 1885 the del (as far as i could see had no cold steam on it at all and at the end on the movie the bttf 3 rr del when it went back to 1985 was semi-frozen and had steam on it. the reason i started this was that i saw it as being movie accurate but now i think it might take up too much coding space and people probably dont care about it too much to begin with..oh well just wanted to see if it COULD be possible is all.
