Travis surely realized he should have stopped once driver went ballistic at him with $97k. He should have just uttered: "Have a good day" or something neutral, stand up and leave. There is no win situation for a CEO arguing with angry people the same way as they do, even if he knows he is right. I believe that's what he meant by "fundamentally change and grow up".
I think the problem here is this: "even if he knows he is right." Considering all we've learned recently how the hell could you ever make Travis Kalanick consider that he might be wrong?
