What you are describing is a legislation of the attitude of the average careless driver in the United States. I should be able to drive however I want until or unless I kill someone, the car should be the thing that keeps me from killing people, and anyone who doesn't use the roadway like me should be responsible for preventing me from killing them.

Spot on, well said. Personally I think inattentive driving is a bigger problem than speeding, but by the time someone is justifying it for themselves by saying they're safer than everyone else, they've lost the plot.

In my experience, the only thing that really feels too fast in a car is going faster than you've become used to driving.

And yeah, how someone talks about cyclists is always a tell.
