As I said before, if you choose to have a gas tax then you need to increase it to keep up with inflation. Other taxes based on percentages like sales, income and property keep pace with inflation. Because of wild fluctuations in gas prices they go with a fixed amount instead of a percentage to keep revenue steady.
The problem is that they don't have something written into the code that says that it grows with inflation. Since increasing it is always unpopular they avoid raising it. When they do they make a big jump so they don't have to do it again for a while. We used to hear the same gripe about raising the price of stamps and even pay phones back in the day.
