I know this isn't the smartest design (the whole swinging of the legs to and fro right at the curb of busy streets and all), but the idea is so much fun!

But yes, I can imagine many people missing their bus while having fun swinging, or not being able to see their bus coming, or not being able to stop the swing fast enough to flag a bus down. Or all of the above.

In a dream sequence, I'd be swinging and swinging and the bus would stop with its door right in front of me and I could just jump! from the swing right onto the bus's platform $1 in quarters hello miss bus driver excuse me smelly guy in the wheelchair ahh how i miss public transportation...
