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!
