A pause on the federal gas tax?

Should there be a pause on the federal gas tax? Some warn the savings at the pump may be costlier down the road. To put things into perspective — what does it mean for drivers? Let’s say you drive a Chevy Equinox with a 15-gallon tank. If you go with Wednesday’s average price of regular unleaded gas in Michigan at $4.83, then you’d spend $72.45 to fill up your tank. If you subtract the federal gas tax with $0.18 a gallon, you’d save $2.70.
