Doesn't this come back to my original point, here's a classic example.

Not being disrespectful, but ...

What if we allow everyone to use hw lipos, What if they become standard like in fws and any Tom dick or Harry uses them.
What if he was doing that in the pits, anyone can make a mistake !! what if we do end up with a fire? to short batteries out I'm assuming, it's in a robot and trying to connect them.
This wouldn't be in a sack.... Bang we have a nasty fire in a crowded pits, in a leisure centre !! Not good in my opinion.

It's the what if scenario I don't like !!! And that's what we base our risk assessments on !
