Government mandates are a big part of it. Also speculators back in the market on the eve of potential cap and trade laws which would make gas more expensive and less plentiful.
Don’t complain. Just check your tire pressure and drive 55 MPH.
Doesn't work. My government mandated active tire pressure monitoring systems already check my tire pressure for me.
As far as driving 55 goes - I tried that once. I got a ticket before I even got out of the subdivision.
