Should I be concerned they can't see me when I'm behind them? I can brake quicker than they can and they can't really do anything negative toward me aside from braking hard. Really, you're assuming all the risk. If something happens up ahead you're going to be totally unaware (the main danger of following closely).

They do this themselves, at least in Europe. It's scary like hell that they follow each other, neck by neck, hour by hour with the shortest possible tracking distance.

Less than one second spacing is illegal in Norway and Germany. Three seconds is recommended.

At 90km an hour (maximum speed for lorries) that is 25m, about four times the length of my car. Is that close enough to get any useful effect?

But can't they also talk to each other over CB radio? Seems like that would make it safer. And of course it's a lot easier to see a truck right behind you than it is to see a car.

Still they block the exits for cars that need to merge. Happened once to me, a train of ten trucks slipstreaming right when I needed to take an exit. Couldn't slow down and merge at the end and the head was already after the exit.

Had to match carefully speed and merge the car in a space I wouldn't have used for parking. And the asshole even blew the horn at me!

Seriously, fuck those idiots doing it. Driven for years on highways and all scary things ever only came from truck drivers needing to save those 10 bucks/five minutes.

So you wouldn't have parked there but you have no problem squeezing between two moving objects 10x your weight/inertia at highway speed? All so you can take an exit (that you were inexplicably in the left lane when you realized you needed it) rather than just take an extra five minutes and turn around at the next exit?

Hard to imagine why he blew his horn.

The lorry driver was in the wrong he was driving with an illegally small space between him and the vehicle in front.

I'm not disputing that. I'm disputing the intelligence of looking at a spot barely big enough for your car that is moving at highway speeds and sandwiching yourself between two vehicles, either one of which could kill you with inertia alone, and then wondering why you might get honked at for it.

not every state has 5 minutes between exit luxury highways

So? Distance between exits doesn't change the fact that what he did was reckless and dangerous.

My uncle did that in his car behind a truck when he realised he had little gas and maybe 50+ miles to the next gas station.

He used his CB to contact the truck in front of him, who welcomed him to draft him along.

During the trip, both my uncle and the driver heard many other trucks call his truck on the CB To warn there was a car tailgating in the draft.

Think he bought the driver lunch when they got to the next town with a gas station.
