>A largish proportion of cop traffic enforcement & safety activity ends in a tow, but we don’t expect traffic enforcement cops to drive tow trucks. These are clearly disanalogous.

But you can't just leave a suspect waiting to be arrested unless they're restrained (in which case, you've already done the hard part of arresting them).
