Planes are bad because you need to land at an airport and there aren’t airports everywhere.
Cars bad because you need to dig in order to make 20 lane wide highways.
When the concepts of scale and efficiency defy your understanding
Literally the most efficient form of land-based transport ever invented. Steel wheels on steel rails have very low rolling resistance.
NAH, it’s bad because you can’t clog up the lines with masses of inefficient, tiny, personal trains.
Also, you have to dig through hills and mountains to lay track - you definitely don’t need to do that for highways (except for all the ones that you do)
Sorry sweetie, you wouldn’t understand, I have a PhD, didn’t you look at my Twitter display name?
