It's neither. The actual reason is lack of biking infrastructure.
Putting a "Share the Road" sign and/or painting some bicycle symbols on a narrow path right next to cars going 50 mph does not constitute infrastructure, nor does it make the road any safer for cyclists.
The road adjacent to the path I detail above is 25 MPH, has sharrows, is very low traffic, and has wide, paved, unused shoulders. It's great mixed bike/car infrastructure.
And even if there was better cycling infrastructure, we'd still need a way to keep people from riding bikes on the sidewalks. Without enforcement, no amount of infrastructure will stop that.
Precisely, that's the whole point of my original reply. That enforcement is not practical, and eBikes make the problem even worse by adding motorized things to the equation.
