No you haven’t. I’ve never seen this. I regularly see people who use the shoulders as passing lanes the moment traffic slows a little bit. Then completely block them. I see drivers trying to get in front or behind an emergency vehicle to take advantage of the rest of the drivers moving to the side with a complete disregard for how they’re slowing everything down. I’ve seen drivers proudly park their car infront of an emergency vehicle and block them, then honk and flip the firetruck off for trying to pass them. I’ve seen drivers shoot at emergency responders because they were blocking the highway. I have never seen American drivers making an emergency lane.
