I have a Yamaha Vino 50cc. It can go over 40 mph. I ride it all over my little town. i have not taken it any further them my own town yet.
My dh and I have 1 car but it is an f150 and it cost a lot to fill up . But we need it for work. I think we don't count as average though since we have one car and we don't take it to work every day like most people. But then we rent cars all the time too.
