People, including me, are driving much less because of the high cost of gasoline. Drop the price and people will drive more, buy more gasoline, and more money will go into the fund.
However, I understand the Fund is open to being raided by the Administration and used for other purposes, just as the Social Security has been raided for many years.
When I left Seattle for KY a few years ago, I went from a five minute walk to my cubicle to a 75 minute drive of 65 miles, one way.
But it’s well worth it.
