This isn't even close to the case - being friendly, having a clean and quiet vehicle, and providing a ride that is safe and not white-knuckle terrifying will all garner a lot more in tips from me than someone careening through traffic to save 30 seconds. I think your hypothesis is baseless.

Agreed. I nearly always tip with Lyft. One of the rare times I didn't was when a driver, in the interests of speed, decided to hit the gas and merge two lanes to the right without a turn signal, because he wanted to get ahead of the truck that was coming down the street. The other passenger (this was a Lyft Line) joked with him about how sometimes you just gotta drive like that. But that kind of driving not only ensured I didn't tip him, it also meant I gave him a bad rating and wrote some nasty feedback. I really don't appreciate having my safety compromised in the interests of saving 20 seconds.
