Uber needs to add an "I'm traveling with children" option. I had a 5 star rider rating until I started traveling with the kids. The kids are quiet and don't make a mess, but it takes longer to get in and out of the car, because the law (and safety) dictate using car seats. There's not much I can do there.
I'd be perfectly willing to pay an extra fee when traveling with my kids that goes straight to the driver to make up for the extra time and to incentivize them to select me as a rider, because they would know they're getting the "kids bonus". And then maybe I wouldn't get dinged on my rider rating just for having kids with me.
