I'd assumed that they were for tourists, and it was a welcome sight to see visitors to the city toodling about happily.

Needless to say, the commuters have figured out how to use this to get on a bike at Union station and cut their trip to work.
If you are going to tell people the truth, you have to make them laugh, or they'll kill you.
