I can think of a few roads near me where 90% of the vehicles do 20-25 mph over the limit all the time.
You occasionally see them out there writing tickets, but never seen an accident in that area.
I would think the data could show that the speed limit should be adjusted up.
Understanding that 2 weeks of the year they need to put out some markers about the holiday traffic creating a full stop.. but they need to do that anyway regardless if the limit is 45, 55 or 70.
Nobody's considered guilty, it's an administrative ticket.
No points are removed from the owner's driver licence because they can't prove who was driving but the owner still has to pay the ticket.
The gist is that it shifts the burden to the accused to prove they were not the driver at the time, whereas when you are pulled over, the police are verifying it right there.
Dynamic restrictions would also be a problem, either by forcing location tracking into every vehicle or relying on (eventually) outdated database or flakey computer vision (cameras can get dirty). Then you need to consider what action to take when a vehicle is exceeding the speed limit. Are you going to disable the throttle or apply brakes? How soon and how hard? Keep in mind that older vehicles don't have this system, so braking may cause an accident. Disabling the throttle might also cause an accident either by upsetting the car with unexpected weight transfer or indirectly because the car could not get away from danger.
And it is only a matter of time before states with problematic budgets end up selling surveillance data about all of us to data brokers or the federal government.
I’ve got as big a tinfoil hat as anyone, but I think this battle was lost a long time ago. Automobiles transportation will become closer to flights, where everything is logged.
