The high cost, installation/electrical issues (while in use and after it is uninstalled.), annd inconvenience is part of the intended punishment.
I’ve seen people do interesting things to avoid getting interlocks installed. In that state if you owned a business an interlock must be installed in all company vehicles. People will sign over vehicles to family members. Some buy a beater car to have the interlock installed on and only start the car a couple times a month to log the minimum amount of starts required for compliance which is checked monthly for an additional fee.
