The multicades seem like cheating.
Off the top of my head:
Robotron (still most addicting game for me)
Star Wars
Point Blank
SF Rush 2049 SE - (linked if I can get this to count as 1) (open to other good racer's with meaningful gear shift and braking...just not familiar with all that is out there)
Punch Out
...well just read the other posts. Clearly I'm going to have a tough time finding a good dedicated Robotron. Thank goodness the mame is pretty good.
