My first thought was that the practice of loading small kids into a basket on the front end of a bicycle and pushing them through traffic is never going to survive first contact with trial lawyers. The tykes will have to be properly restrained in a tested and certified roll cage and wearing approved safety devices – at which point it will be fabulously expensive and nearly impossible to move.
My second thought was climate-inspired. This was a December morning in Ohio, with about an inch of newly fallen snow on the ground. That makes the whole concept a hard sell. The last time that I rode my bicycle to work, I got caught in an afternoon rainstorm on my way home. I haven’t ridden my bike to work again since. It would take some pretty hefty incentives to get me to opt for a bicycle in sub-freezing temperatures or in any type of precipitation.
