You cannot compare our system with theirs. There, if you are caught (insufficient money in the cash card to deduct toll charge, defective card reader in the car, etc), their land transport authority will send letter to your house to either pay the toll charged plus penalty, or send your vehicle for inspection if the system does not detect your card reader in the car. You cannot ignore the letter because the consequence is severe - can be charged in court.

Here? Who is going to help TnG collect the unpaid toll if drivers do not have to go through toll gate and simply drive off? Issuing summon/letter won't work because people will just ignore it. If JPJ/polis summon can be ignored, what chance does TnG have in recovering the owed money?
