Cheapest city with moderately decent public transit is probably Washington DC. With an average home price comparable to the one I live in without public transit of about $600,000 more than my current home. Even if I didn’t own my truck outright (8 years old, 58k miles) and the price of gasoline doubled, my payback period for 100% free public transit is greater than infinity with a 5% cost of money calculated in.
It’s a bit like solar. I’ve run the numbers, and had others run the numbers, and the conclusion is that it would require replacing solar panels twice before I made back my investment, even with a 0% loan for the panels and install.
I’d love to be part of it. I’d love to have European-style public transit. Even in the few places where viable public transit exists in the US, it’s not affordable to move to those places. shrug
Me: Should I buy a prebuilt 3D printer?
Reddit 3D printing sub: Oh, heck no. I put mine together for $18.22 plus some spare parts from seven printers I got of craigslist for $1 from some widow. Only took me three weekends to do it, plus a couple hundred hours to update the firmware to match the parts and troubleshoot it.
Me: Uh, so does it print better than the one I could just buy?
Reddit: Well, I’m still tuning it for all my filaments. I’ve been through about 40kg, and I’ve got a trashcan full of benchys though. The last few have been pretty good.
