When gas get to _________ will you stop driving?

Seems like every time gas goes up people lament or rage about the cost of it, I remember this going on way back to when I was in Jr. high. When gas got over a buck people said they would stop buying it; they didn’t. When gas hit 2 bucks and over people said they would stop buying it; again they didn’t. Then it moved to $2.70, then $3.25 but still they bought, they griped like hell but they purchased gas and/or drove their vehicles. Where is the line in the sand for you? Once the price of gas hit where would you absolutely not pay, and would it be because you simply refuse or it would start to take food off the table or put bills at risk?
