Neither option is ideal. Shop by bicycle with proper carriers and
bags. Much greater range and/or speed than walking. Lower costs than
bus journeys without waiting to their timetable and poor/inadequate/
indifferent service. Bicycles are low noise, low impact, healthy, low
stress, go-anywhere transport. A secondhand bike has already paid its
carbon dues with honours and compound interest.


Not exactly.

Cycling raises one's energy expenditure by several hundred
kilocalories per hour. It has been surmised that each kilocalorie of
food requires the use of 7x to 10x that amount of energy in the form
of fossil fuels to grow it and get it to the table. This brings the
"MPG" of a bicycle down into the range similar to that of small cars
or scooters.

You can take short
cuts through housing, industrial and pedestrian areas where cars often
aren't allowed. No traffic jams.


Only because there aren't many bikes.

Out in the fresh air enjoying the
exercise, the birds and nature. Instead of suffering the toxins and
stresses of driving in the isolated bubble of a noisy and smelly
vehicle.


Listening to my favorite talk radio shows or CDs, while sipping coffee
in climate-controlled comfort.

Often with difficulty finding handy parking or paying
expensive parking charges at your destination.


And much more often, not.
