Something the developing world needs to work on, is on Car TIRES, to research the tires and create the most beefed up tires and at the same time take some weight out of regular cars [talking about gas/petro/diesel cars...Specially the developing world needs to work on this...I am talking on tires that last years and are specially good for in the country where there is no umpaved roads....That's what they need to research...And how to recycle them...

Anyways i always felt that cars are to low, they sit to low, they need to go up some more...

the more modern they are the more they sit on the ground...
