> California either needs wider roads, or to mandate narrower cars (it seems to have worked well enough for emissions...) Taking the opposite view, mandating narrower roads (or, refusing to widen existing narrow roads) has worked great for opposing the problem of car growth in some countries. If you watch a busy intersection in Japan you see a ton of incredibly tiny cars go by, and it's no coincidence that backstreets in major Japanese cities are often nightmarishly narrow alleyways, sometimes without sidewalks so you even have pedestrians sharing the already-tiny road. For example consider this side street near a touristy zone of Kyoto: https://www.google.com/maps/@35.0010412,135.7662851,3a,75y,202.16h,58.68t/data=!3m6!1e1!3m4!1s8_LbqTQ65DZcGd6l8ruLjA!2e0!7i16384!8i8192 https://www.google.com/maps/@35.0010412,135.7662851,3a,75y,2... You can see people walking right along the road. An average person would not feel comfortable driving with a big car, nor driving aggressively nor at a high speed, on this road. Taken combined, this is what makes these roads safe and pedestrian-friendly, even though at face value a road without sidewalks might seem the opposite.
