Also, yes, the hyperloop isn't directly relevant to Mars for that very reason - the atmosphere is annoyingly thin from a reentry point of view (enough that you have to protect against heating from it, but not enough that it can be used to bleed off all that velocity from orbit) but that means it's not really an issue if you want to push something fast through it. That said, I wasn't making any comment about the hyperloop itself rather the parent post's comments about why digging tunnels on Mars might be necessary.
Not sure why my posts attracted downvotes though (not necessarily from you), but whatever.
