In Auckland alone 30% of all trips made are under 3km, that same distance can be ridden on a bike in 10 minutes or less fairly easily. IF Aucklanders could be encouraged to jump on a bike for short distance trips, there is a potential for significant reduction in traffic on the roads.
I think it is important that we choose the right tool for the job, anything that is short distance and lightweight a bike can easily be used for. Going to get more milk, an ice cream or a 6 pack from the local store can easily be done on a bike without the need for a car. Thats one more car off the road!
You may not think this makes much of a difference, but a car emits the most emissions while it is warming up, so your 5 min trip to the dairy can produce a lot of pollutants into our air!
Ten minutes on a bike isn't hard, in fact its fun, so next time your about to grab the keys just to get some milk, try the healthier alternative, it'll be good for you and the environment!
