Will never happen because of our (USA) HUGE natural/oil resources. Our land is truly blessed. (And no, i am not religious but one cannot deny how rich our land is.)
Now, if a future President decides to ignore what we have and pursue some dumba$$ agenda resulting in us going back to importing tons of oil and be reliant on Middle East, then yeah gas prices may go up. IF that happens, then yeah, i will buy a cheaper transportation vehicle and my LC becomes a weekend car only. In fact, right now, i drive 100 miles everyday...and mostly i use my minivan for that.
