shopa 5pts Kei cars are a special class of cars in Japan. They are limited to an engine size of 660cc and have vehicle size, but not weight, restrictions. They are made by many different Japanese car companies and they are mature designs that are reliable, and get up to 60 mpg. They can cost less than $10,000.However, they cannot be driven in the U.S. because they don't meet collision safety requirements.I believe that adding my crumple box invention to a Kei car will allow it to pass U.S. collision safety requirements. www.safersmallcars.comPlease help me promote this idea.
