Environment!!! Lets talk of it less and practice more....
I have done my bit.. I have borrowed a bicycle from a close friend and make sure that I travel to & fro to the office on this basic motor invention. This not only saves a lot of fuel but also helps me keep fit!! Add to that no traffic woes and lesser contribution to the ever increasing pollution! Yes it does cost you those extra few minutes but the investment is worth it!
I urge the readers to consider this option.............
