I say create a Department of Tire Inflation Police. The police stop cars and check tire inflation ,if the tires are not properly inflated, the driver loses his /her license and the car is taken off the road. Now there is a real gas saver. Plus having the added effect of creating employment for these police.After attending a proper tire inflation course for say three years the driver can be reinstated with his car. More jobs for teachers teaching this course, teachers must be certified through the Government Tire inflation Academy.
