Lets not waste too much time comparing a sport that happens in a closed, controllable stadium with a WRc event.

How many people are involved in running a football or basketball game? A few hundred?

There would be quite a few thousand involved in the running a WRC event.
- on public roads
- using police
- using ambulances
- using medical helicopter
- using marshals
- bringing people from all over the world

etc etc

You can't compare the scale of one to another.....
