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".
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.
I'd call that extremely dangerous...
Focussing on speeding seems to ignore that there are other serious issues that contribute to the outsized danger on US roads.
