Forgive my arrogance, but nothing presented in that article should be such a big blocker. Spare parts for the traction gear sure, but none of the computing "problems" make any sense.
It's not like hard real time systems aren't available. More concretely, they talk about running a DOS virtual machine on a laptop to download logs from the cars, but there's no way that protocol is so complicated it couldn't be re-implemented reasonably.
This sounds more like "It's cheaper to just buy old stuff off ebay than it is to actually care about this system"
I'd wager it is technically a "cheaper" problem, but I'd also consider the axis that this is public transit, an industry known for being neglected budget-wise. Reverse engineering/reimplementation with competent parties may be laughably out of budget.
No, but like roads, public transit leads to greater economic activity and boosts GDP. Good public transit also increases social and financial mobility, makes other clean air targets easier to hit, and decreases medical costs [0] while increasing the number of financially-productive hours a citizen can work - because a healthier citizen is a more economically productive one.
America seems utterly incapable of grasping many second-order effects. For another example, look to the ROI of investing in the (coninuously underfunded) IRS [1]
Yes, thanks for elaborating. I seem to be not clear in my point: that public transit is subsidized and it's a good thing, we should not expect to see an immediate profit from it, and should not expect a commercial company willing to invest into it.
I appreciate the clarification, my mistake taking your original comment the wrong way. I'm a little reassured too - what seems to be an Americanism (things that don't turn a profit aren't worth doing) feels like it's seeping into my locale as well, so I may be overly sensitive to it. It's nice to be told I was wrong in this instance.
