If your car is in the garage, no one can see the license plate. So what is the difference?
It’s not a blight if you can’t see the car.
“..furthermore, garage doors will remain open 24/7, 3-6-5...”
Home owners will have 60 days to demolish their garage. If they don't do it in that time the State will do it for them? Well, that's one possibility.
If you have visitors, their #'s will also be scanned. Lots of data on vehicles/owners and will show who's there, who might be associated or visits that address etc.
This data is used and kept for future references. They're tying all these systems together. If you owe taxes, fees, fines, judgements or whatever, they'll know it.
