Here’s a wonderful advertisement for mass transit.
Every mass transit I’ve ridden on in the US was filthy and crowded with people I was warry of.
A friend, a pretty big man, lost is car and thought he’d just use mass transit in Tallahassee as it was feasible from where he lived. (He was paying off bills for his wife’s cancer treatment.) He was assaulted several times by black women who just seemed outraged that this white man in a suit was riding “their” bus. He said he hated every minute of it and couldn’t wait to get another car. (This was during the Obama years when race relations seemed to be at an all time bottom. They improved a lot during Trump’s presidency. I have no idea where they are now as I’ve moved and the blacks in my rural area are just fine...but there’s no mass transit as there’s no mass.)
I’ve been on clean mass transit in the US, but usually that was when new vehicles were put into service.
