California's population is about the same size of Canada's, a country larger than the entire US.
While many people do live in cities, many live in, and outside cities, in rural areas.
Rural areas which support the farms you seem to like. Farms do not live in a vaccuum, and require an entire infrastructure of people working, and living in these areas, including schools, etc.
But outside of this, I noticed you completely glossed over climate as an issue, ignoring inclement weather for most of the year. Your map of warm California is irrelevant here, and does not discuss this.
Canada has very excellent urban planning, and often has grocery stores near by. That only helps at certain times of years, and only helps in dense areas.
This is part of the problem.
Electric cars are an awesome solution, yet what I see always is hard core environmentalists harming positive change. An electric car is far, far better than gas, yea? Is it?
Then holy hell, just drop the blather and embrace it, and be happy change is happening.
Get behind the positive.
We have vegetarians manipulating the climate crisis to get their way (no beef is not bad for the environment), we have the bike/anti-car side doing the same.
You want truth? Here's truth, and you saw it with all the covid political stupidity.
Push too far, and it backfires...
