Enforcement raises so many questions. They would have to get into issues of blocking the GPS rcvr in order to conceal how many miles are driven. That leads to questions on parking the car in a garage or under a carport, trees etc.
Next comes inspections of one's home by ODOT, to prove that one has a garage. ODOT would then have to look at driving patterns and history for evidence of fraud.
I can see the enforcement of this tax procedure getting to be very expensive and entrusive. Far better to keep the simple consumption tax.
The first law to be passed will be one excluding all elected representatives, police officers, state employees, and legislative staffers from being required to be fitted with a box.
