Corrected entry: Why is it that when in the first film when Doc grabs the door handle of the time machine when it comes back to normal time with Einstein in it and gets hurt by the extreme cold, but when he grabs the hood of the DeLorean in the second film to give Marty the walkie-talkie, he doesn't have a reaction at all?

Correction: This is a question, not a plot hole. And to answer, the DeLorean has been to the future at this point, where it could have gotten any number of modifications we don't know about (we see the hover conversion and Mr. Fusion, but who's to say he didn't do something about the freezing? Maybe some kind of instant heater if the car drops below a certain temperature?).
