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).
