I don't see these being true unless you live in an area where getting around on a bike is actually realistic. Basically not USA, even the metro areas, except for maybe a handful.

They're already losing billions each year. You want them to lose more?

I think Uber is in a great position already with the dramatic increase in cost of new and used vehicles and people's ability to work from home multiple days a week or permanently. It may already be more cost effective to Uber over having a car. Obviously bussing is an option but Uber matches the flexibility of a car much better. I'm going to generalize here but you might spend $700/month on a car. A monthly payment of $400 for the car (or equivalent purchase price/useful life), $100/mo for insurance, and $200/mo on gas. In a given month there might be 20 to 25 business days. For $700/month you could instead spend $28 per business day on Uber and break even, and if you work from home Uber comes out cheaper. This is without including parking costs in metropolitan area's, repairs, license fees, tows, and of course the insurance deductibles as well when an accident eventually does happen. Plus you get the comfort of not driving and ability to get things done on the trips. If we are drinking we end up Ubering anyways as well so we don't have to drive home.
