That's one reason I avoid public transit. In theory I like the concept, and it's vital for many people. Reduces traffic congestion, provides transit for people without their own cars, lowers pollution, etc, etc. And for nearly 20 years I've been able to use public transportation at little or no cost, due to being disabled.
But the riders are often revolting. It's like going under a bridge and spending time with the unwashed homeless.
I used to ride a commuter bus from the Seattle suburbs, for only $.25 on a disability pass. Once inside the city center all buses were free for everyone. You just got on and rode. It was some liberal perversion, that promoted downtown business.
From my downtown stop I'd take a free local bus to the VA hospital. But so did lots of other vets, many of them in rags. It was scary.
Some of them would roam the bus aisle, ranting & yelling incoherently at everyone. The bus drivers remained oblivious to it all, never intervening. Naturally I felt sorry for my fellow vets, their minds gone. But I also had to wonder why no interventions could be done, to get them into homes or something.
And so to this day I have a disdain for public transportation, even though I can use it for pennies here, as I did in Washington State.
