Noting that the "police cruiser" was deliberately detailed to not look like an official Toronto police cruiser. There are several possible reasons for that: avoidance of "paid duty" fees, lack of script approval, and quite possibly not wanting their rented vehicle to be mistaken for a real cruiser for safety reasons unrelated to any other concerns.

I would imagine that if the cops aren't completely stupid (a big if) they would want to avoid a repeat of Gabriel Wortman's massacre.
