"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.
50 vs 49 or 51 may be arbitrary, but overall there's a relationship between speed and car accidents which makes setting speed limits a real judgement call.
