I always read it more as a “hacker” thing - he found a loophole and was exploiting it to show it existed, a “look what I can make this do”.

I’m sure Jobs could have had all the legal handicap plates he’d have wanted, if the point was just parking in the handicap spot. But it wasn’t.

>this was done so he could park in disabled spaces

That makes no sense to me. I can't think of a place Jobs would ever drive his car where it would matter if he could park at a disabled spot. He had his own spot at both Apple and his home, where else did he ever park often enough for that to matter?

Personally I believe the explanation that he did it to avoid the ugly license plate. It mirrors how he refused any stickers on the Mac, when all other PC makers had to put the "intel inside" on theirs.
