"I hate these damn bike lanes. Screw your studies. I'm not reading that"
"Cut gas taxes. I see no reason why I should pay to support public transit"
"Fuck speed limits. I'm proud to break the law"
This sense of entitlement is insane.
re: first study
Results. The relative risk (RR) of a road collision occurring on the beltway after (vs before) installation of speed cameras was 0.73 (95% confidence interval [CI]=0.63, 0.85). This protective effect was greater during weekend periods. No differences were observed for arterial roads (RR=0.99; 95% CI=0.90, 1.10). Attributable fraction estimates for the 2 years of the study intervention showed 364 collisions prevented, 507 fewer people injured, and 789 fewer vehicles involved in collisions.
I looked it up, it looks like the Beltway is functionally equivalent to a US interstate. This makes some sense, as speeds on interstates are going to be higher than on arterials (and the arterials in Spain probably aren't as bad as our stroads in the US).
