Driving in city is sometime a terrifying experience with occasional lack of parking spots. At some point, the road quality was so terrible that it was extremely bumpy.
I prefer trains when possible, but waiting for trains can be especially long, and I am sometime bothered by people, who might be mentally ill. Also, it's very noticeable when someone smoked weed, but that's about it. There's a distinct lack of transit employees for the most part.
Increasing train frequency and service would reduce the amount of time waiting, as well increased operation budget for human interaction issues. Upzoning around transit station will make trains more sustainable. Increased social service and effectiveness will take care of peripheral issues that's not the transit agency's job to fix.
