I agree say this is generally true in the United States, where driving discipline on highways is basically non-existent. Although I would stop short of calling it "extremely dangerous".
How many people would need to die each year for it to be considered extremely dangerous? Literal wars have been started over fewer deaths than the US road network racks up in a year. OK I’m being facetious but the extent to which we’ve normalised 40,000+ deaths a year really is remarkable, can you imagine the reaction if smart phones killed that many?
But speeding-related fatalities accounted for 30% of traffic fatalities in the US for 2022. Which implies there are plenty of other issues, such that I think saying "speeding is violence" doesn't really do anything to address the problem.
Roadway injuries and deaths are both leading causes for many demographics and the US has a death rate three times Canada's, per capita. More than 4x the UK's.
