The problem with there not being a central emergency cut-off would be when you allow custom circuit boards to supply PWM signals to speed controllers. That would effectively bypass the emergency controls, and allow your robot to operate at any time, only considering there's power to all necessary components.

Yes there are a lot of things that could effectively be used to shut down the robot, but we are talking about a parade situation where children especially are going to run up and look at the shiny thing on the road. I tend to look at these things from a safety first, good ops second, and let's just get it running third. From where I stand it's not safe and it's not good from an operation standpoint (unknown effects from different power sources). But it will get it running.
