People can fly to Texas because they rent a car or use taxis/rideshare once they arrive. Houston in particularly has absolutely atrocious walkability or transit lmao
People who arrive by HST should also be able to rent a car or use taxis/rideshare.
Assuming ticket prices are similar to Amtrak Acela prices or current non-HST Amtrak Texas prices it will be a little faster than flying for about 1/3 the cost. It will be almost 3x as fast as driving for a bit more than the fuel cost for the drive.
If there are enough people who want to travel between those two cities to do the kind of things that people fly to those cities for, then it should be viable and successful.
