I use a rideshare app when travelling between cities, which I often do. This saves money and is often very fun. People evaluate you as a driver, and it is important to keep a good score. I let 3 people go on the backseat of my relatively small car, which is usually not an issue. These passengers are usually complete strangers to me.
The app does indicate my car model, so people can see I drive a small car, even though I don't think they often look at it. I could also add this info in the description, but I'd rather not do so because that will likely get me fewer passengers and might still not be read by people.
I've had problems a few times with people who are clearly overweight, because they get fairly uncomfortable on the backseat, and then go on to give me a poor evaluation. They did have the option of looking for another ride with only 2 passengers on the backseat, and they could have reversed two places just for themselves.
Usually, the front seat is empty. But one time, a friend in a front seat offered to change seats with someone in the backseat so they'd be more comfortable. The "assigned target' didn't get the idea, let another passenger take the front seat and complained in the evaluation.
Besides that, the problem review-wise also happens when someone takes the front seat before I can do anything or there are too many overweight people such that having one or more of them in the back is unavoidable.
It is really important to me to avoid bad reviews, and I think I can do better if people would just take the front seat if that gives everyone more room.
When I encounter obese passengers on a rideshare, how to politely get them to use the front seat?
