As far as I am concerned Uber's days are numbered. I am in the insurance business and I don't know of any insurance companies that will allow people to use their personal car to drive for Uber and still be covered during the times they are not driving with a passenger, or simply driving for personal use. The only policy they can get is a taxi/livery policy which costs thousands. Uber is telling drivers that their personal insurance will cover them, but it's not true. The only time Uber's own insurance covers the driver is when they have a fare in the car. Otherwise, the driver is screwed. There is litigation pending in many states regarding this. As the accidents pile up, the truth will spread. There is a new insurance that is partnering with Uber called MetroMile, but it's a pay as you drive thing.
Anyway, enjoy the Uber delivery while it lasts. Or at least while they have drivers who don't know what they are getting into. And they'll probably never know until it's too late because Uber doesn't have a customer service phone number so no one can ask them.
