Maybe not constantly, but don't tell me you haven't.
Last summer I took the bus for a month because my car died and I wanted to see if I could get around town without a car. Town is 5 miles away and during that time there was construction going on between our place and town, and many of the pedestrian crossings weren't working. An average trip to town on foot took about 1.5 hours, which isn't always practical timewise.
We were trying to take the bus back from town and the bus driver decided to argue with a young woman over her age. She was boarding the bus using some kind of low cost I.D., and the driver wanted proof of her age.
The bus was Calcutta packed, we were 30 minutes later leaving and it was August. Two blocks from our house my infant daughter vomited all over herself and where we were sitting on th bus. I think she got too hot and became nauseated.
Two days later I found another cheap car!
