Today Uber's default UI suggests tipping with options 15, 20, and 25%. 3/2023

If the minimum amount increases to over 15%, the market resolves true.

Deadline 9/2026

I'll be testing on Android. If there is partial rollout, I'll wait for something clear that's broadly applied to Uber users.

If Uber goes out of business this is a no.

If there is no global default I will judge based the median lowest default suggested tip across people I ask.
