Then it relies on enforcement to catch you operating an illegal vehicle on a public road
Unlike e-bikes, your vehicle has a plate, so needless to say, if you get caught speeding on a public road by a camera and your vehicle was registered as having had the thing turned off at the time in the database (i.e. it shouldn't be on a public road), you could imagine getting an additional charge similar to operating a vehicle without a license plate or operating something that's not road-legal.
It makes total sense to me
let's say somebody else said "There SHOULD be an expectation of privacy from the authorities when operating a motor vehicles on public roads on which you need a license to drive"
Is there some reason I should side with you over them, or just your opinion? If the courts decided that there was an expectation of privacy on public roads, would you agitate to change the law so there wasn't?
Sure! It would make infringing on road safety much more difficult thus reduce your chances of getting run over by people who are speeding, running red lights etc. And if you're driving, I think everyone would enjoy less maniacs on the road.
Motor vehicles killed 3566 people every month in 2022, that's the death toll of the 9/11 attacks every 25 days.
Do you not consider reasonable to have an expectation of innocence when going about your business?
