Technical speed limit enforcement absolutely can be done in a way that respects autonomy and privacy. A car can have a camera, a one way data link for maps, a gps, and/or a transponder for signals from speed limit signs preventing it from exceeding the default speed limit without a positive signal/mapped limit or active intervention from the user. None of these things require an uplink, and if you cared about autonomy, privacy, cost, and safety you'd be pushing for such a solution as well as actually caring about the telemetry in almost all new cars without these features.
Cars are costly primarily because they are much bigger, much heavier, and much harder to maintain than they need to be. If one didn't have to deal with the near certainty of getting t-boned by a ford ranger or suv doing 20 over the limit in one's lifetime then a microcar capable of 40km/h with a simple lap belt would be safer than the average 1.5t sedan full of airbags (and the requisite limitations on user maintenance) is now. Additionally with options other than lugging around 2-4t of steel and plastic and covering half the city in vast seas of asphalt available, 80% of people would get to their destinations faster.
They're also more likely to live next to major roads, again negatively impacted by speeding motorists.
Since kinetic energy is a square of velocity, slowing cars down - even a little - both significantly increases the chance of surviving a crash and also makes it more likely you'll stop in time to avoid the crash in the first place.
Also interestingly, lower limits often reduce congestion and increase total road capacity. I'm not sure how safety at the race track works out, but skilled, predictable drivers in well maintained vehicles with race marshalls and huge run off areas probably makes any comparison awkward.
Exactly. People driving closer and paying even less attention because “driving slower”. Lack of attention and driving skill is what leads to accidents, not speed. I do need to say, though, the speed limit in the city, between pedestrians, I personally treat as saint. But outside of the city, especially when there’s almost nobody around, well, that depends but never reckless.

The only race track I’m familiar with, is the Nordschleife. Not much run offs there.
It wasn’t like that when the limit was higher. Lower limit, people tend to get closer.
I don’t see this _so often_ in Germany, neither in Belgium.
If you tried that on an interstate in the US, you would end up with annoyed semi trucks tailgating you, and passing motorists might assume that you are impaired.
When I don't, usually I get a greetings postcard from a radar.

The goal is to discourage driving over time by making vehicles prohibitively expensive, by posting lower and lower speed limits over time due to "climate change", and to continually revise the standards to separate people from their ability to leave their homes as quickly and permanently as they can convince their populace to accept.
