Assuming the rides are comparable, the article has a table which includes price/km (weird) of Lyft: $7.99, Uber: $8.36, and Waymo: $11.22. On that data, Waymo is roughly 40% higher, so way more than just a tip.

Assuming you didn’t upgrade to a different tier or pay for priority to get your uber faster or a nicer ride.

Uber also can increase the cost of the ride on you with unexpected routes or time. Yes you can complain, but I am sure plenty don’t even notice.

The math isn’t wrong, but it’s not so black and white.

I’m in the camp though of “I would pay double not to deal with a human”

in my limited experience, you're not usually tipping a percent but a flat dollar amount of like $2-5 per ride, so $3 on an $8 ride basically removes the price difference between lyft/uber and waymo

Only about 15% people tip https://www.businessinsider.com/1-percent-uber-riders-always...

Important caveat to that study from right at the end of the article:

the data set used for the study, while massive, was limited to 2017 data. [...] Uber only added a tipping function to its app in 2017

So the study was either before you could even tip in the app or soon after and when it was still new.

A more recent study would interesting.

My thoughts exactly. I usually tip well - too well if I’m drinking and that’s usually when I’m taking an Uber.

it's funny, but tipping is one of the things many people will pay more to avoid.

About the same.
