If the hyperloop is going to be elevated/grade separated/30 feet up _anyway_, how is it not practical at all?

They're literally exactly the same (center to center). 162 miles.
If you actually are using new RoW (again, which I suspect will really be the case) then 290 is even more direct.

Just look on google maps. 290 and 71 have many turns along the way.

I thought the whole point of the hyperloop is that it wouldn't have to slow down for (sufficiently large radius) curves , as it could cant up into the curve.
On the micro-scale, I10 and 71/290 have similar radius curves, especially around cities in the way.

That curve doesn't appear to have any worse radius than several spots along I10. Especially if you (for instance) follow Hempstead/rail RoW.

Gross distance is an _incredibly_ important design consideration, and in no way superficial.

If you're going above the hill
regardless, then neither.

Then let's see the calculations. What are the projected construction costs? RoW costs? Operating costs? What are the projected boardings? Where's the signed agreement with TxDot for usage of the I10 RoW. Where are the station locations? What are the ticket costs? Their site seems to stress cargo even more than passengers. How much cargo demand do they project which is so incredibly speed-sensitive?
The fact that the team can't even put together a proper website (duplicated paragraphs).

doesn't fill me with confidence.
