That's for all vehicles, including ones that are expensive to own and uncommonly used for rideshare. "Small sedans", which are pretty common for rideshare, cost 42c/mile. These costs also assume depreciation based on buying cars new. Costs would be quite a bit lower if they were based on buying 3-5 year old used cars, for example.
