I didn't even think about the oil changes, despite the fact that I've talked to drivers that are putting in 500 miles a day. I also didn't realize people were that big of dicks - the customer side of Lyft will ask you what the driver needs to improve if you give them four stars (which I think I've done twice, and that doesn't include the friendly lady that got completely lost during a blackout). What's hilarious is the first (only) time I took an Uber, the driver was astounded at how good my rating was without revealing to him that I had literally never been rated so of course I was a 5-star passenger.
The leases are a whole 'nuther animal. They seem to be a truly peculiar, truly predatory instrument (although I've ridden with a couple drivers for Lyft for whom they made sense, but they were also driving like 90 hours a week).
