I would have to admit that even I, I public transit nerd, would prefer an empty subway car. I also don’t like driving when I’m stopped dead in traffic, or biking when it’s next to a highway with no lane, or the bus when I miss my transfer, or walking when it’s pouring rain.
I guess my point is that everything has a worst it can be. The idea, though, is that a city should offer all of them so that you can choose. And a subway at its worst, unlike driving at its worst, will still get you where you need to be on time.
I generally agree but I'll caveat that subway at its worst can be far worse with trains going missing. "Metro apologises" is a running joke around the north east of England for how bad its service became in the past 15 years.
But 40,000+ Americans die in their cars (and run over by others' cars) every year. No subway caveat is ever going to beat that. And at least it's obvious that subways going missing is a _very_ solvable problem. We've completely given up on making driving safer.
EDIT: Sorry, re-read the context, and I think you were countering my claim that a subway will always get you there on time? Yeah. You're right. Subways can absolutely be delayed, go missing, stop running, go on strike, etc. Sorry for going off the "rails" there. :D
No worries, it happens to us all. I was mostly venting at the shocking underinvestment of my local public transport infrastructure and seeing it degrade over the last 20 years!
