Hogwash. ~10k of the 13k families in Peachtree City, GA own a golf cart that maxes out at ~15 mph. (New ones cost $10k+.) And Peachtree City is a suburb, not a retirement community or college town. Americans will absolutely buy small, fun vehicles if they have safe places to use them.
New research finds that NYC's congestion pricing program has reduced collisions. "The introduction of the Congestion Relief Zone is associated with fewer overall crashes." doi.org/10.1093/aje/...

This isn't an obvious conclusion, BTW. Congestion pricing reduces traffic, enabling cars to move faster. All else being equal, faster cars are more likely to crash and cause injuries/death. But w/congestion pricing, all else isn't equal. I.e., total traffic volumes may fall, reducing exposure.
