Last time I took Amtrak out of LA Union Station, it broke down but luckily was able to pull into the next station so people could get off and find another route. I stayed on and after about 4 hours we were towed back to union station.
So you need to work within their framework. Take the smoke breaks with other passengers. Note how the door works. See where the nearby road is.
And then do a runner.
Why anyone would pay 100x the price to have the same experience is beyond me.
But that decoupling from the need to be somewhere at a time is quite hard.

Wikipedia says that they're primarily used on the east coast, so that's probably why I've not seen one. I've ridden all over the lines west of Chicago. I'd love to do their new Chicago to Miami line sometime, so perhaps I'll have the privilege.
There’s a wall…
No wall, nothing, just you, your roommate and a toilet for you two.
