Unofficial study of level of upset for my kids during commute:

I used to live in an area where the only option was driving my kids to daycare. Now I moved, live carless, and only have the option for public transportation and bike with 2 bike seats. Here are my estimated statistics. Car: 30% chance of crying or upset at getting in the car seat or somewhere along the ride. Public transportation: 15% chance of getting upset in the stroller or being bored during the commute. Bike: 0% chance of upset. Kids have been upset getting their winter clothes on, or getting out the door, but they’ve absolutely never been upset once they see the bike or during the ride. There’s also a 78% chance of them singing during the bike ride.
