No, when you go somewhere, chances are greater than not that you won't be in a heated indoor parking garage. So you have a 2 way remote with a range of thousands of feet, it lets you know that you car has started. Some people do start their cars in their garages, but either open the garage door a bit or they have hoses that fit over the exhaust and vent all of the fumes outside (not very common, but they exist).

Deals with the vermin of various kinds before you get in there.
