Cars are fucking deathtraps and a massive waste of public and private resources.
I've always been a proponent of cutting down their use. Also, more stringent licensing requirements until we invest in effective public transportation (which is a hard fight already as manufacturers and even police have interest in dangerous vehicles being sold to the public).
Also, why the fuck do we have so many gigantic trucks on the road for shipping? Invest in fucking rail freight.
And, on a personal note, my grandmother still has her license and there's no fucking way that's safe for anyone.
