Imagine thinking this is acceptable on public transportation.

I agree. I'm not going to advocate for public transportation if I take the risk of running into a weirdo like this, or even worse.

At least in my car, I'm guaranteed to not run into weirdos or gross conditions caused by ill adjusted members of society.

Unfortunately that falls under a different category. Fuck cars is about advocating for good public transportation and making cities easy to enjoy without a car. You're asking for better mental health care and services for the homeless. There are very few people that would actively do this type of thing if they had any other well lit up space they could do it.

Don't forget public transport robbers!

3rd world country person checking in, I feel safer on my car, especially when it is late at night.

That's an opinion you can have if you want to I guess.

You have set an unreasonable high threshold for when it's acceptable to want to change the situation.

If these people were driving, they'd be irresponsible and selfish in their cars too. Right now she's just gross. In a car, she's a dangerous weapon.

If you are so scared of other people to the point that you refuse to use public transport then you are just paranoid. Crazy pictures and videos taken on public transport are just extreme examples, not the general everyday experience of using public transport.
