I do OK, but I don't need Uber as a full-time gig like most people on here do. I have two other part-time jobs, one with flexibility, so I simply drive when I can, maybe 10-15 hours per week. I drive an EV and get free charging for a year via Toyota, so I don't have the same costs that a lot of drivers have. My goal isn't necessarily to pay all the bills, but more to pay for the car, insurance, and build up my savings. I'm also not the sole earner in my household.
Having said that, I pretty much accept whatever they give me. For the most part, my rides get bundled. Sometimes I have to wait a few minutes, but it's rare that I wait more than 5 minutes. The vast majority of the time I get sent a new ride before I drop off the current passenger. However, when I use the Destination Filter to go home, I usually spend most of that time just driving home without a passenger (so that's the dead time). About half those instances I get a fare in the direction I want to go. I find it is not worth using the Flexible Fare because that seems to shut off the filter for some reason, so I use the Fast one to ensure I can just get home. BTW - it often wants to send me on 90 or Storrow to get home, but I always stay downtown as much as I can to better increase my chances of finding a fare (e.g. - ignore the direction and get it to re-route). That works way more to get a return fare than taking the faster routes on the map.
My thought is that if I had to do Uber full time then it wouldn't be worth it due to the wear and tear and other costs of the car itself, but also because you essentially pay double taxes with Uber (you pay both the employee and the employer portions). Yes, you can deduct mileage (or other costs if you go that route), and I keep a manual track of that because I drive more than what Uber tells me I do, but still...it's less than my other jobs on a net basis, even if it is more on a gross basis. However, doing part-time isn't so bad. It's money in the bank, but if I had a regular gas engine...man, I don't know, that would kind of suck. I'm already thinking about when my free charging ends next year. As a part-time job, though, it's OK.
BTW - if anyone is thinking of a new car, MA has a $6500 rebate for EVs specifically for rideshare drivers. Due to the current administration's restrictions on how to get the $7500 tax credit, the MA program isn't so bad. In fact, you can add the $3500 rebate for EVs on top of that $6500 for rideshare drivers. And if you make below a certain amount, that $3500 can become $5000. Also, I charge publicly as I live in an apt building, so I don't have access to home charging.
