I decided to start driving my son's daily driver, the Hoondavan (2008 Honda Odyssey) weekend evenings. 7 passenger vehicles (6 riders) are eligible for XL fares, which can be a bit higher. It's got nearly 190k miles, so depreciation isn't a concern. Gas mileage isn't great, but I typically turn down rides that are more than 15 miles away. Longer rides usually mean a long ride back to town w/out a fare. Longer rides on Uber can also be comically cheap. Other times, they try and send offers that are inconvenient, low priced, or generally require lots of driving for low $$ (think 2 hours 1-way for $40). I mostly drive weekend evenings. Sometimes 10 until midnight or 1 AM. Other times I'll start at 5PM & drive until midnight. I've done some weeknight driving when it's been busy (FL spring break & after easter was spring break for the northeast)
From what I can gather, Uber has gone to essentially a reverse auction model to pay drivers. Their algorithms will price passenger rides as high as possible...but they will start filling a ride by finding a driver who will take the fare at the lowest possible price. They've increased customer rates/mile each of the last 2-3 years, but average driver pay per mile has been cut consistently. It's still good enough to make decent money under the right conditions ($30 to $50 per hour)...but if it's not busy, they essentially ask you to drive for free. There are likely some drivers who may not appropriately factor in gas and/or mileage depreciation. There are others who may rent cars & don't appropriately value their own time when things get slow (accepting fares that translate to very low $/hr earnings). There's plenty of times where I only hopped off the couch and started driving because surge pricing went into effect. When it's super slow, $20/hr can be a challenge at times.
Tips tend to equal between 30% and 35% of my earnings. I'm usually driving tourists around either to/from dinner/drinks and hotels. I tend to talk a bit w/customers & recommend places to eat/drink and things to do. Some passengers are quiet...but most are friendly, engaging, & interested talking.
My highest earnings were a 3-day concert weekend, followed by spring break week. Concert goers tipped really well. Spring breakers, not much at all...but it was busy & they were all mostly all XL fares. Concert nights aren't really as lucrative as they should be due to the fact lots of drivers from out of town show up. Once they show starts they all just sit accepting low fares until the concert ends. Pickup at a concert is also a bit of a crapshoot. You could accept an early fare before prices spike...but if you get delayed w/pickup you'll miss the surge. Some shows I can get 3-4 pickups and 3 dropoffs. Others, I may wind up doing just one each.
The money has been very helpful in taking care of bills. More often than not a single customer/ride makes it all worthwhile. For example, last Friday it got super slow early-evening. I was about to head home, but wound up making $75 from two ~10 minutes rides (significant cash tips)....which equaled my earnings from the prior 3 hours.
I'll probably keep driving. It'd be smart if I sold my E91 so I don't have to "borrow" kiddo's car when it's time to drive. SWMBO's GX460 uses too much gas around town to be logical. A newer E90 or E60 would be a nice replacement...but something XL would be much smarter. I've been toying with the concept of a Mercedes R350 (gas only...no diesel for reliability reasons). I'd probably get better tips for the luxury, but they're more thirsty & operating costs would probably be higher. Another Honda Odyssey or a Sienna would be much smarter. Also, people tend to really like power the power sliding doors of the odyssey. It makes loading/unloading very easy. With that said, I really don't want to have a mininvan as my primary driver. Not quite sure what I'll do, but here's a snapshot. Some nights I drove 2-3 hours, others 5-7.
