If considering a scooter and the fun factor is important then i think they are good choice, for people without kids, or say people who have real parking issues, consumer wastefulness issues? the scooter is a great choice. I want one because they are fun local summer travel. Not because they are good on fuel which they may be, but not for their size/ability. My car gets 60mpg this linked scooter gets 100mpg so it has a large real world fuel saving potential.
