We've seen Uber discussed here and not just in context of this incident, but much worse stuff. It would be interesting to see what comes of that...
But taken it on its own, this is what apologies should be like and not the "I am so very sorry you all feel this way" type apologies which then usually also proceed to shift blame (circumstances, others, acts of God, bad mood, etc).
Now whether he actually feels this way or not or this is just good PR I am not sure. It remains to be seen.
