Never ending cycle of inflation versus what alternative? Right now we have these periodic very large gas tax increases to catch up with inflation followed by years of decline in the buying power of the Highway Trust Fund. I've actually just read a bit more on the proposal and they do propose indexing it to inflation... but only after increasing the tax by 65% to catch up with inflation over the last 20 years. Basically the choice is to either have it indexed to inflation or else have these periodic hyper increases to catch up with inflation anyway.... or come up with another tax system.
Of more concern would be the proposal to introduce an expensive and intrusive open road tolling system to track all our movements and charge us a per mile tax.
We don't need open road tolling if there is a mileage tax... we all have odometers and we can read and I know at least in my state we have yearly odometer readings and odometers are read whenever cars are sold or registered, so there isn't any reason why we can't just read the odometer and pay a tax instead of having all our movements tracked by a multi-billion dollar electronic tagging system which really infringes on our privacy also.
