Interesting, I've rode a bike during the six months I spent in Santa Clara & San Jose and never had it stolen.
However, I did notice that there were a lot of bike parking / bike racks that were awfully missdesigned/overengineered. There were racks that could be opened to put your bike in but many people did not know that so they locked their bike to the rack but when you opened the rack, you could simply slide the lock out. In many cases, the bike was only locked to the rack, which meant you could drive away with the bike without ever picking the lock.
I've made the same mistake for about two weeks, until I noticed that this retarded bike rack mechanism left my bike completely unprotected. Afterwards, I always checked other bikes and I frequently found others that you could just pick up and drive away with.

One of the best, if not the best, bike rack designs is this here: https://www.bikecitizens.net/wp-content/uploads/2017/03/Good...
Very simple design, it can a whole lot of bikes and it's as secure as it can get.
