substitute for a bike. It is, in fact, less flexible, as it will be
harder to take kids along, carry large amounts of groceries, etc.
Its much greater weight will make it very difficult to horse up
stairs and so forth. It does have one large advantage: it takes up
little more street space than a bike.

calculated at about 7 to 1.) But if you're figuring car parking, you
have to allow as much room for access lanes as for the parking spaces themselves.
These things look like they have a footprint of about 2 sq.ft., or 21,000 per
acre, compared to the usual figure of about 100 cars/acre. The actual figure
will be no more than 10,000 due to access lane requirements, but it's still
about 100 times better.

while travelling, they take up almost no extra space.

will complain that they are too slow. In fact, though, 12 MPH is not
an unusual speed for "casual" cyclists not wearing Lycra and not
pedalling $4000 bikes.

My own view is that they must be treated as bicycles, and tolerated,
if not allowed, on sidewalks, as long as they are ridden responsibly,
which means slowly, and always in deference to pedestrians.
