The national average right now for unleaded gas is $3.16. Not that it won't happen, but gas prices would have to rise another 27% for it to get to $4 when the cost of crude oil is at an all time high. If you listen to the news conference, he doesn't say that he doesn't know what the cost of gas is, but that he hasn't heard that "experts" predict the prices to go up to $4/gallon.
Again, like him or not, but if you think the existing administration does not know about the price of gas, then it is not me calling you out, its yourself.
