Well, the good news is, they'll face retribution if the tow cable attaches; there's no way the speeder will stay level if you pull it off of the track.<br/><br/>Edit:  Also, I can't remember the rules exactly, but an object of a speeder's size that is immobile (helpless) probably has a single digit Reflex defense (if not a near zero one) so hitting it with a tow cable at point blank is probably trivial even for a non-proficient and potentially wounded shooter.
