I believe that was a demo of the "Crew Dragon's" emergency jettison method should anything go wrong with launch. One would hope it should never have to be played out during a real-life mission.
The acceleration of the vehicle is impressive. Not the best time for a shot of coffee.
Inside the vehicle is about as Jules Verne as it gets:
Yes, it was a test of the emergency abort system. I guess taking a wild ride is better than dieing if it works. But I didn't expect the thing to tumble as wildly as it does. I would be concerned about the parachute lines wrapping around the capsule and failing to deploy correctly.
The tumbling seems to have been predicted and catered for. It's not just a capsule, Sol. That is a fully controllable spacecraft in it's own right. If the parachutes failed in any way, I think it's high thrust rocket engines can be fired to reduce closure speed with the ground and cushion the landing. That might even be in the test queue. Every conceivable velocity/state configuration will have a solution programmed into the machine's computers. Remember, these are next-generation devices and they need to adapt instantly to situations where the failings of human judgement require the latest in artificial intelligence development to step in.
