I feel sorry for all the shut ins, the young parents with kids who may have to dress them in winter and trudge out in the snow to get their mail and those with disabilities. And what about anyone with a short-term illness - the flu or whatever? In addition there are parts of the city where there is barely place to install these units. Snow clearance is already a challenge with parking meters etc. We don't need more clutter near our sidewalks.
Change - we have to accept it - but not when it is a step backwards!
