Just passing a law is mostly virtue signaling. The tough part is passing laws that actually work. Why do we allow convicted drunk drivers to do diversion, which seems to rarely work? Why are they allowed to drive while suspended with hardship waivers? Why are they allowed to own cars? Why is anyone allowed to sell them cars? Why do cars not require that a valid license be read by a strip or chip reader in order to start? Why do we not pay for and perform actual traffic law enforcement so we can catch these intoxicated drivers before they kill?

Lots of ways to skin this cat, but all of them impinge on windshield perspective motorist entitlement complex, so we sit on our hands and refuse to do things that would actually make a difference in our rate of CARnage (up 58% since 2013, btw).

I think it also hits on this definition of a serious crime: a serious crime is one which I personally would never commit. Since all legislators regularly break traffic laws, it's not serious to them.
