Big Brother Gas Tax

Did you know within the next two months the government is going to float a bill to add a tax on your gas mileage? There would be an electronic device attached to your car to let Big Brother know how many miles one drives and where and when they go.
Only a thought here but those who use their vehicles in a line of work would be hurt the most. As a former on the road salesman I drove anywhere from 60,000 to 70,000 miles a year trying to be productive. There were twenty-three other salesmen in our firm. Now, try and compute the rest of business in the USA that utilizes this type of action. It's a mortal sin to come up with this tax. May the proposers rot like a dead opossum in the middle of the road.
