i guess it took 15 weeks in your papern coud talk about i guss they were hoping they wr gangto get some tips. But how did that then have such a big effecton drivers? It couldn't have brought too many drivers into the into the pool. After all, they found out whyl actually musable, don't tip. And it ended at back being similar. No, i think that's right. I mean, this is, this is expectations, right? In beliefs. That's why you get such different results across ride share tipping and, say, yellow cab tipping.
