That’s rare enough to not keep people away from public transport. Speaking from experience in Portland OR, it’s more the daily low level stress of having to keep an eye out for the meth crazed lunatics around you. There always seems to be one and they’re wildly unpredictable.

That's another way of saying that we need more public investment (in addiction intervention programs, for one), not less.

BART crime is up over the past decade. People don't avoid BART because of that headline with the chainsaw man. They avoid it because of everyday crime and violence.

I'm sure it's similar for many other metro transport options in the USA. California in particular has a rough go for many reasons.

It doesn't even have to be something bad or happen to you. One "my buddy had his bike stolen off the light rail" and several people will be turned off of ever trying to use it.

The "crime" story has been so twisted by propaganda and lies-by-statistics that you'll have to forgive me for saying that I can't take your word for it and will need numbers. Truthiness certainly can drive people to make poor, (unfounded) fear-based decisions.
