City may give some vehicles the boot.

The City Council today will consider a resolution that would allow police to immobilize vehicles whose owners have more than three outstanding parking tickets.

Under the proposal, police would be allowed to place on one wheel a metal “boot.” The boot could be removed if the owner pays his tickets, plus a processing fee, by phone with a credit card or debit card.

My question: should we call it a “smart boot” like they do in Denver or something more local, like “tire slippers”?
