I speed, effectively every day, just as do most other people, because many roads still have a speed limit of 55mph from the 1960s and the expected (and safe, partly because of this) speed on these roads is 70-80mph.
Dangerous drivers are the MANY people I see every day who are on their phones, not looking at the road, with bad lane-keeping practices, who change lanes without using blinkers, or make erratic and sudden movements.
Dangerous drivers are the MANY people I see every day who tailgate and then pass aggressively via weaving between lanes, passing on the right.
Dangerous drivers are the MANY people I see every day who camp in the left lane while going significantly below the expected average speed for the lane, causing some people to feel it necessary to pass them on the right and obstructing the flow of traffic.
Speeding probably isn't good, but it's not even in the top 5 things I would be most concerned about on public roadways in the US from a safety perspective.
As a passenger or another driver on the roadway, I'd much rather be surrounded by attentive drivers with both hands on the wheel who are speeding than inattentive drivers with one hand on the wheel and the other on their phone watching a Tik Tok video and texting their friends while cruise control is set.
