Generally the driver gets the majority of the ride cost, but their earnings vary a lot by region/time. If you’re just asking if it’s a good job, then the answer is a resounding no. I did it for a few months a couple years ago, and I have a friend who has done it as his full time job for the past 6 years or so. No change that Uber/Lyft makes is ever designed around benefiting the driver. You can safely assume that any new policy is going to make you earn less than you were before.

At the end of the day, you are not fairly compensated for vehicle wear and tear, fuel consumption is not factored properly for all rides, certain arbitrary locations pay more or less and require unpaid relocating to actually land rides, etc. The best is when you take a 2 hour trip only to find out after drop off that you aren’t allowed to pick up new rides in that area and that you need to spend nearly the same amount of time getting back to an area you’re qualified to drive in. I think that one at least has been mostly resolved since I drove years ago, but you get the idea…
