gas price going down

[dubob]

the problem is gas tax is over a dollar a gallon so gas can't really go much cheeper

Sorry - that's just not true with regard to what we pay at the pump when we fill our motor vehicles.  Were you perhaps refering to some other place taxes are applied to motor vehicle fuel? 

Utah adds 31.1¢ to a gallon of fuel (Link) and the Feds add 18.4¢ to gasoline and 24.4¢ to diesel (Link).  That's a total of 49.5¢ added to the actual cost of gasoline and 55.5¢ added to the actual cost of diesel.  You can argue the value to the country at those rates, but it isn't even close to being over a dollar.
