I recall an incident back in the 2004 elims where 494 got tangled up with 121 and ended up tearing out wiring out of 121. There was a
rather ugly thread about the whole thing too over it.
While FIRST isn't Barttlebots things do get pretty hardcore out there sometimes and in spite of FIRST passing rules to prevent such incidents (kind of like what the NFL keeps doing) it will come up again.
