@2fd7551e To take the car example.  I would imagine you'll
a) Have a bunch of people demanding exemptions for their expensive 'classic' car
b) Have more people concerned about the monitoring data/rules being misused by the government or sold on to third parties

If you can precisely define how the rules/data will be used (with non overridable mechanisms to stop them being misusued), anonymise the data (using auditable techniques) and block exemptions (with subsidies if necessary) then fine.
