yeah, consistent enforcement would make everyone happy. at least you'd know what to expect. well said.

the point of my first link was to show the relationship between speed and injury/death. those extra 10mph are meaningful. the fact that it's in Florida doesn't change the relationship, and I only linked an old study simply because my quick searching only had newer studies showing basically the same thing in link unfriendly pdf format.

the second link is absolutely anti car, but makes its point with data, and that data is consistent with other trends. would it be better to just quote part of their abstract?

> In 2018, pedestrian fatality rates per km in the USA were 5–10 times higher than in the other four countries; cyclist fatality rates per km in the USA were 4–7 times higher. The gap in walking and cycling fatality rates between the USA and the other countries increased over the entire 28-year period, but especially from 2010 to 2018.

and yes, enforcement isn't the only or even the best way to address this. road design is a better option.
