That's what I wondered, Candy.

Also, do the windows always roll down when the temp inside always gets above 88 degrees?

Say there is no dog in the car, but the car will heat up anyway and the siren starts going off. Seems like a hassel to run out, shut the siren off, roll the windows back up just to have the car do the same thing once the inside heats up again.

If it's a device that has to be turned on by the officer, it seems like it defeats the purpose. If they can remember to flip a switch, they should remember to just take the dog with them....
