Clown Car doesn't always knock people over

[69andahalf]

This might not be it, but when you drive the Clown Car or Segway, you don't need to hold the keys to move, it will go on its own. With Segways, I'm pretty sure by letting it coast into a person it will just harmlessly bump into them, the same may apply to Clown Cars.

I haven't driven the clown car for awhile, but I don't remember coasting into people and it not working. I was definitely trying to push them and they were pushing me back. It could be if you initiate contact with someone through coasting, you can't knock them over but I don't know jack about the code.
