Interesting. In SF, most of the time I just walk outside when my car has arrived and jump in. Then I get to my destination and jump out. The next time I take a ride I may do things like hit the 5 star button and the No Tip button but that's it. Most of the time my start and destination are already available from a quicklist because whatever time-and-location-search Lyft has is damned good.

I don't want to key in numbers and shit. Not even a QR code?

For this standard experience, I'm willing to sacrifice the tails: driver getting lost on way, driver being a dick. The rarity makes that worth it. Happens to me maybe once in 20 rides. Looks like you have a different calculus.
