This assumes that the reputation costs are comparable in weight to the acts that they commit. Based on the past year and what I hear about Uber's growth[0], I'd argue that their reputation and their valuation are quite uncorrelated, but it's hard to know the truth.

Rather this assumes reputation costs times risk of having those costs while undertaking some action is comparable to gain from this action.
And theoretically the only people who can regulate banks are the banks themselves.
Funny how you hear that argument every time a horrible industry is trying to keep profits high by eternalizing costs: meat packers in 1900, tobacco in 1950, oil and gas till today.
The only possible costs would be if they're made to pay a price in a court of law, which seems unlikely since the woman who was killed had a bike with her, and it's unknown if she was on the bike at the time, but she's been described as a pedestrian outside of a crosswalk. Clearly Arizona authorities just don't care about safety.
I wonder whether food companies (like the meat packing industry in Chicago) said the same thing before the FDA was created in 1906; i.e. that reputation will just regulate the industry to not sell mislabeled products, or spoiled or adulaterated food.
The ironic part here is that Uber already has a strong reputation for skirting the law and not caring. Their response and the following audits will be worth following.
