We need to have to Speed Limit signs one in MPH and one in KM/H . Also distance signs .

For example 50 MPH / 80 KM/H , DALLAS 1 MILE / 1.6 KILOMETER , Exit 200 FEET / 61 METERS . This will create more jobs for workers because they are puting up signs . Also this will help education . Students in school use the Metric System in school but forget it because it is not  use any where else . Also if workers are travelling from Mexico to the United States their car speedometer might only be in KM/H and how will there know how fast they are driving in MPH . This will also increase tourism . 99% of our immigrants come metric countries .
