Ok on the drivers can we use like Motorcycle helmets for protection? and how amny drivers do have to have?
you can wear whatever you want, within reason and safety.
2 drivers, 1 coach and 1 robocoach
I was asking ,not trying to be rude, Do we need to have a rotation and how many inside that rotation?
you can have as many driver as you want and rotate them however you want.
Be careful with the motorcycle helmits. if the ref cant see your eyes than he wont allow it. ( ie. tinted visor)
Or no rotation at all, if that’s what you want. I’d advise having a backup driver available in case someone gets sick or something.

I race dragsters, so I’m going to wear that helmet and fire suite. hmm…may get a little hot though at Florida regional. 
We thought about getting Flight helmits and Paint them like the “Top Gun” ones. The only problem was they are really expensive without looking really cheap and crappy. At about $400 each (for a good looking one) we were forced to scratch that idea.
We were going to put the visor down (if dark) when our team was called and whenever and just raise it for the match. If it was clear we would keep it down cause there would be no problem.
