One thing I always found pretty disappointing about the live version (and just down right sacrilege in DCUO given it has the most iconic Super Vehicle in comics with the batmobile and it's various variants) was that we never got super vehicles, now I know, a lot will say well they're too big, or how would you fight with them, well they needn't be and you wouldn't.
They'd act purely as a means of travel (unless there were a separate mission type for them where they could have built in weapons or run races or other various scenarios) and they could range from the size of a motorbike, to a small car and basically act like a faster version or superspeed or flight that's only usable on the world map.
I dunno, it was just always a dream, especially with how many Villains/Heroes I make that are natural/tech that I always feel weird giving SS/flight/teleport to get about.
