If you want tips, clean your car. I clean my car weekly (for myself, not my passengers) on Sundays after my long Saturday night drive. You know, you typically average a couple bucks at random times, it's not really expected with Uber. Anyway, I changed it up a week ago because I was going away on Sunday, so I cleaned my car on Saturday before heading out driving for the night. Out of 11 rides, 9 tipped! Made $37 in tips that night. I got SO many compliments (more than usual) of how clean my car is and how nice it smelt. I feel like that contributed to my tips. Maybe it was a coincidence, maybe it wasn't. I'm definitely going to try it again this weekend to see how my tips play out. TIP: Maintenance is key. Clean your car weekly and it won't be a chore when you wait weeks or months to clean it.
