Car gets 450 mpg

Yes, there's a car that gets 450 miles per gallon of gas.
It's a railroad car!

Say you weigh one ton.  A train can take you 450 miles on just one gallon of diesel gasoline.
Here's the good part:  you don't weigh a ton.

This is ten times more fuel efficient than trucks. And it works for trains being less polluting than passenger cars too.
