Problem is it’s much easier to have someone just take a measuring tape to a car when ticketing and get the length.
You can get the footprint, sure, but you have to ensure you measure from the same point twice, and that you’re pretty much perfectly perpendicular.
You could also have a database of makes and models but then you have to have somebody set up and maintain the database and that causes all sorts of headaches

That’s how we got camelback houses with more floors in the back than in the front. Measuring just length will make the cars fat.
