Bike lanes and roundabouts aren't going to save us from ourselves. The data is clear, the science is clear, whether everyday folks believe it or not. Intervention and regulation is needed, but this stands to lose powerful people lots of money. Hence money funneling into conservative politicians and efforts to politicize the whole issue. Now you can "own the libs" by being anti climate change efforts.
The politicization of scientific issues just hurts us as a whole. If not now, later.
Of course, a big chunk of the voters hurting us now won't be around later to deal with the damage they've caused.
