Or, get this: make it so people don’t take the car. Most of the accidents that involve serious injury or death involve cars or some other fast, motorized vehicle. Why not make more bike and pedestrian infrastructure?
Of course, I agree. But living in North America, this would never work because NIMBYs would keep any politician who even makes that suggestion out of office.
The fear of change, even if it offers unlimited freedom, safety, and convenience, has such a tremendous influence in our infrastructure's design.
I once asked a city planner why we don't stop people from parking in bike lanes. His answer was that "we wouldn't have bike lanes if we didn't compromise", stating that the pushback at the idea of removing on-street parking would basically kill the idea of safe cycling infrastructure. That's the kind of small-minded BS we have going on here.
