I disagree.

The reason i would let the betteries die out is noy because of fear of damage to the other robot, but there is no telling what the out of control robot could do if it bounces of and schrapnell starts to fly. Specialy with a spinner like that. with boxes like storm II you could risk it but not with that kind of shape as greenwave.

This could pose more of a risk to public and arena personel than just wait till is stops by itself.
