Presumably this is intentional -- Uber could raise prices and make more money, but right now they're choosing to keep prices very low in order to undercut Lyft and the cab companies with the assumption that having a monopoly will return more profits in the future. At least anecdotally, here in SF Lyft is almost always more expensive than Uber.
I think almost certainly their profitability is dependent on a future of driverless cars, and I'm sure that's what they are pitching investors. Fearfully, since their survival means going driverless and they are now losing $800 million a quarter, they will race to get driverless cars on the road, it will be rushed, and it could be reckless. I'm thinking the two driverless cars filmed blowing red lights in SF recently…
There are plenty of times of year where I'd be wary trusting a human driver from the bay area in a Minneapolis snow storm much less a computer designed by them. I can see how it would be easy not being able to imagine difficult road conditions when you spend your whole life in a place where the worst weather is a tiny bit of rain.
Multiple instances of running red lights right when they start testing? To me that says driverless cars are decades away and some people are so optimistic that they aren't going to see it before there are several tragedies and driverless cars are legislated away.
There are lots of very common driving mistakes that are orders of magnitude more common than stopping for a red light.
