My biggest problem with Uber/Lyft is how the costs are incredibly obscure to the driver. I think that sucks. With Postmates, for example, a friend of mine was making $15 - $20 an hour riding his bike. That's ok money! Especially given the characteristics of the job I mentioned above. If he'd been driving a car, it's not really ok money.

I'm eyes wide open about the downsides of many of these jobs, especially the ones that involve using your own car. I just want to mention the upside because it's important. It has helped a really save a few of my friends butts at really tough times in their lives. I don't want to lose site of that. Optionality is important.
