Okey dokey. This piece by @MarkCasci is very, very silly.

Seeing as I haven't done a #Loopyhype thread for a while, I think I'll explain exactly why below...

Just in case you aren't familiar with my battles with the pseudo-scientific, snake-oil peddling charlatans that try and flaunt this long-debunked junk, here's a reminder:
The piece starts as it means to go on - by making no sense whatsoever and repeating a lie without questioning it.

What the hell difference does 7 versus 26 minutes make for people? And Hyperloop is ABSOLUTELY CERTAINLY not going to be cheaper than high speed rail.

Well, here is some made-up stuff... Let's look at these numbers, shall we? #Loopyhype
4000 vehicles/hour means 0.9s separation between them. It takes 15s to brake to a stop from 155mph, assuming the system can decelerate at 0.5g (you'll get whiplash much faster than that).
Assuming the same acceleration, it will take vehicles 500m to get up to speed and 500m to slow down again.

So for each access shaft, you'll need 1000m of parallel tunnel to get vehicles on and off the primary tunnel. And 0.9s separation doesn't leave much space for error.
