Trouble is society has become very convenience orientated and generally lazy.
I live next to a 3 schools and there are local residents who love no more than a 1 minute walk from home to the gates but, they will drive the kid(s) to school and back! Many drive to the shop at the bottom of the road and back, literally a 15 second drive on way.
I have always enjoyed fitness of all types but as I can no longer run, cycling has filled that void. As soon as I am happy to be able to keep up a brisk pace, my distance increases and cycling makes sense. It cheaper and better than driving providing your commute consists of suitable roads/paths that you are happy to ride.
For me I find people find it admirable when others do it but I find the following excuses common;
'its dangerous, you can't trust car driver's',
'you will be sweaty when you get to work , carrying clothes etc, too much hassle'
'it can't be nice when its raining'
'if you get a puncture your stuck!'
'have you seen the cost of bikes these days! my car didn't even cost that!'
