>>>"It is necessary, as in America, to put the receipts under the car park to everyone who has parked the car incorrectly."

This situation occurs:
Parked incorrectly, got out of the car and drove a sheet under the yard (an old receipt or a similar paper printed in advance at home). The inspector goes and sees that there is already a sheet - a new (second) will no longer hang (you can not punish twice for the same thing). To check on the basis of all the cars with sheets (he hanged himself or still someone from the inspectors) - long, and given the annual increase in the number of cars - it is impossible to check all. According to the zonal principle (one inspector is attached to the territory and only he can pay the fines here) it will also not work - you will not mention them all, and on your records / bases also not enough to check the time of the worker (especially because the machines come and leave).
Well, the man (the driver) will attach himself under the court "the penalty sheet", while in fact not receiving a single penalty.
This "American system" will simply not work in our country...
