I use Flywheel and taxis occasionally: red lanes usable and curbside already available pickup at SFO. However, each time it's a horrendous experience.

Vehicles are bottom tier. Cab driver will always insist on just being like "What's the cross street?" (Bro use the satnav). Way more expensive.

Wasn’t flywheel a response to Uber?

I believe it was. Had a bit of controversy at the start with the guy fighting some taxi companies over it, but overall it does the job fine. The problem is that the taxis themselves suck.
