Even on a commuter bus or plane, if someone has a medical emergency and needs to get off right now, the bus will pull over or the plane will land. In this design you'd have to just sit there, helpless, until the vehicle reaches its destination. Heck, even if you're a doctor in the next seat you wouldn't be able to get up and help your fellow passenger.
Landing a plane will guaranteed take more than 35 minutes. With the hyperloop, it's simpler and more efficient to just have EMTs called and on station when the car arrives.
Actually, an airliner can usually descend and land within 10-15 minutes in an emergency, assuming a suitable runway is close by. There are more smaller airports with 5000 ft runways that don't typically handle 737s or larger.
The problem with emergencies at major airports is that between EMTs and fire services inspecting the jet, that runway is out of service for at least 30 minutes.
On a normal flight a 737 flies an approach at under 180kts but the approach limit is a lot faster. In a cardiac arrest type situation, the pilot may decide to fly a faster approach into an airport with medical services available. They would still touch down at the normal speed.
They discuss this in the paper. In the event of a medical emergency the pod will proceed to the destination as normal, and paramedics can be waiting at the end. In the absolute worst case you are looking at ~30 minutes before you can get to medical attention. That's not obviously worse than the time it would take a plane to descend from cruising altitude to the nearest airport, land, and taxi to a gate.
Except you can get first aid assistance in a plane (they ask if a doctor is here, and they have a number of drugs on board). Keeping the person alive until paramedics arrive is key to handling emergency situations, and I don't see how you do it with the Hyperloop.
Yeah, I believe this is the best point in the argument against pod transport. Even taking doctors out of the equation, if someone were to go into cardiac arrest on a plane, pretty much anyone on the plane would be qualified to operate an automatic external defibrillator and all flight attendants are required to be trained in CPR. The opportunity for first aid in this situation is the difference between life and death and it is unavailable in this pod design. 3 minutes without oxygen to the brain and serious brain damage is likely; 15 minutes without oxygen and you're pretty much guaranteed never to recover if you aren't already dead. If you have a cardiac episode on the hyperloop and need to be resuscitated, there's a good chance that the only good that those EMTs will do when the train arrives at its destination is to remove your dead body from the train.
