Trust me, they still do the checks in the southern states, at least CA. A couple of months ago, I was driving from San Diego back to LAX, and the Border Patrol had the I-5 completely blocked around Camp Pendleton. They were making everyone drive past officers very slowly so they could peer into the vehicles. The overhead marquis sign said "Border Patrol Checkpoint Be Prepared to Stop."
