Should the government raise the gas tax, no I don't think so. The reason being that we already get taxed so much on everything else we do and buy in day to day life because the government can't stop spending, so then it's up to us to pay for it. " At some point in the not-too-distant future, gasoline sales won't even have the potential (which they have today) to fund road maintenance. The aversion to tax increases now makes even the most rudimentary repairs difficult or impossible; in the future, the U.S. may not even have the option of turning to a gas tax increase because the sales base won't be there." (https://www.bloomberg.com/view/articles/2015-07-22/raise-the-gas-tax-before-it-s-too-late). I agree with this because the gas tax could not be enough soon with electric cars coming up and becoming more relevant.
In my opinion I think that we should increase the gas tax. Now it is rare that I agree with raising taxes but in this case it makes sense. We see that with this gas tax it would help with the infrastructure of all of our roads and bridges and tunnels. Plus gas is super cheap right now so it would make sense to tax it more. "We now pay for the maintenance and construction of our interstate highway system, bridges and tunnels -- plus many state and local roads -- through the Highway Trust Fund. (We have discussed this before here, here, here and here). The fund is financed by a gasoline tax that has been stuck in a time warp. The last time the tax was increased to keep up with the cost of construction and maintenance was in 1993, to 18.4 cents a gallon. But now the fund is being starved of funding because the tax wasn't indexed to inflation. Adding to the strain is weather that has gotten worse for roads because of hotter summers and colder, snowier winters." (https://www.bloomberg.com/view/articles/2015-07-22/raise-the-gas-tax-before-it-s-too-late). I agree with this because we need the funding to fix our roads and other infrastructure that we use day to day
