Responding to concerns about the gas tax (“Per-gallon tax outdated” Feb. 25). The math is current, reliable and miraculously accounts for vehicle mileage and weight.

Your Prius driven 3,000 miles at 50 mpg requires 60 gallons of gas, costing you $0.24 per gallon or $14.40 in gas tax. My Escalade, driven 60,000 miles at 15 mpg, requires 4,000 gallons of gas, costing me the same $0.24 per gallon or $960.00 in gas tax. No need to weigh cars or measure emissions, which would be another tax.
