I would pay a lot more for a car that was guaranteed not to have anyone playing loud music or aggressively trying to beg from me while I can’t move. If I could sit down, that would be an added bonus.
For one, that sounds like a problem of a system that is too dysfunctional to enforce the rules they already have.
But how much more, really? How much would it cost to have someone drive you to work every day? Is that your limit? Or is it faster to take BART, such that you would be willing to trade off door-to-door convenience and pay even more than that for a first-class car?
also that sounds like a quiet coach, which i think is a thing more often than full on first class?
When I took the train often, things would fill up in this order:
Quiet First Class section
First Class section
“First Class” section would typically be no noisier than the “Quiet First Class” section, you’d just pick Quiet First Class first, on the off-chance that a loud person had a first class ticket
(Typically somebody having a phone meeting, you would not fucking believe the kind of things people will just say in public when they forget they’re in public. I often fantasized about what it would take to become a corporate secrets dealer; can’t accuse me of theft when you’re giving them away for free on the train! You can get the same effect if you’re just sitting for a while in an up-scale café.)
