Since each capsule layout and interface will be different.The example, I suppose, would be how NASA astronauts trained for launching on both Shuttle and Soyuz. Won't they also be passengers, not pilots? - Ed Kyle

But you have to train for contingency situations, evacuation, loss of pressure, aborts, etc.
Back in the Mercury/Gemini/Apollo days, human skill was important because they had such limited control systems, and there was even some hardware that was accessible and meaningfully field-repairable/modifiable. Now, in a modern spacecraft, if something goes wrong, and there isn't a programmed response, and ground control doesn't take care of it, it's terribly unlikely that it will be anything that the so-called "crew" can do anything about.

Loss of cabin pressure. Loss of communications. Fire in cabin.Survivable to trained crew, deadly to untrained individuals.

Why are you assuming crew of modern spacecrafts cannot access hardware and field-repair/mod it? Volvo didn't win CCtCAP contract...
1. Water egress.2. Loss of cabin pressure.3. Loss of communications.4. Fire in cabin.

Fire in cabin.1: If you land in the water, or otherwise in a hostile and remote environment, the safest thing is probably to just stay in the capsule until it gets retrieved.2 and 4: You're in a suit. Stay in the suit, stay in your chair. Let automated systems and ground control detect and put the fire out / pick and execute the fastest reasonably-safe way to get you somewhere you're not dependent on the suit for survival.

Right, you've landed in the water and the vehicle is slowly filling and sinking. Rather than getting out and living, you're going to stay in and drown.Same with a fire on landing. Or, say there's a fire in the vehicle in orbit. A trained crewmember could pick up a fire extinguisher and put it out. Or simply put something on it to smother the fire. Or notice it's an electrical fire and yank the wires. None of which an automated system could realistically be expected to do. But instead you'd have the crew sit and die.Same goes for loss of cabin pressure. A trained crew member might be able to find the leak and plug it. Instead, by your rules, they'll just sit by and do nothing.
Not to mention that Soyuz-13 crew died because an oxygen valve was difficult to access and they had no training on how to do it. even the latest F-22 fatality had this problem. If that poster thinks that training is unnecessary, he shouldn't be close to any dangerous activity (that means no driving, btw).

{snip}If you've landed in water, the crew compartment is taking on water, and the vehicle is sinking, that means you've suffered at least three separate major system failures (the launch or targetted reentry failed, the main pressure vessel has lost integrity, the air bags have failed). But somehow, the crew is still alive and concious, it's only taking on water slowly, so they still have time to climb out and swim for it.
If you say I should be being prevented from driving, then I say rather you should require a 6-week emergency procedures course on any particular model of elevator you wish to ride in. Neither the Dragon V2 nor the CST-100 will need a pilot, nor any other crew.
Even at the full $108 million/seat, since this is money that's being spent in America, it's probably a better deal for American government than spending $80 million in Russia, just by counting the consequent immediate increase in tax revenue (income and sales taxes, as people take their salaries and profits home to spend, giving other people salaries and profits to spend, etc.).
