Idk they could lead to significantly _more_ traffic

As driving becomes easier to access due to an influx of vehicles, could lead to a Jevon's paradox situation where there's more driving demand, and more autonomous vehicles on the road, often circling because they know they're likely to get another rider soon, causing more congestion than today

The lobbying done by these companies also clearly favors car traffic over public transit & pedestrian traffic. I'd much rather optimize for better walking and biking traffic than car traffic
