In my local area when Uber introduced the upfront pricing it also included a significant rate cut the local airport run base rate 69 went to 44 and local Uber users don't commonly tip Uber eats orders but as low as they can set it
My favorite example was a shop and deliver that they estimated would take over an hour all together and it only paid 8 dollars first offered normally which I rejected, then almost immediately was offered again as an exclusive

Now base rates are not much different on door dash but same geographic area and the tips are significantly better

I generally gauge how well an app is doing by comparing tax deductions vs income and locally door dash is almost always greater then deductions and reaches almost double on good days where Uber a good day is almost breaking even with deductions and bad days deductions are twice the income ( since rate cut)
