"Americans worried about their country’s sky-high rate of crash deaths haven’t had much to cheer lately. "
This is untrue.
America's motor vehicle fatality rate per billion vehicle miles has gone from 3.35 in 1980 to 1.27 in 2023. It's a dramatic reduction. In 1980 there were 51K fatalities in the US, in 2023 there were 40K. In 1980 there were 226M Americans, in 2020 there were 331M.

For comparison, Australia has done even better : https://en.wikipedia.org/wiki/List_of_motor_vehicle_deaths_i...
But in Australia there are still lots of articles bemoaning car fatalities without acknowledging the dramatic decline in car fatalities by distance traveled and per capita.
Enforcing speeds for repeat speeders may well be a good idea though.
