Couldn’t find this in the rulebook. Are your opponents allowed to bump into you when you do pre loads ?
There’s a Q&A that I couldn’t find that says (iirc) that robots are granted no protections while at the loader.
So technically, yes. HOWEVER, if you want to bump an opponent at the loader, you must be very careful not to knock over whatever they are stacking the cones on, as that is very much illegal.
