I don't have a problem with roads getting fixed. But I do have a problem that all too often such earmarked funds "disappear" before they reach their intended purpose.
I also don't mind that the rising cost of fuel may cause someone to pause before they make an unnecessary extra drive somewhere. But that extra cost will negatively affect the average person taking public transport just to get to work.
As a reference point, petrol in England now costs about $7.00 a gallon! The government there (and in western europe) slaps high taxes on fuel to reduce pollution and petroleum consumption. It works.
