I had a driver in a Ford F-150 do this in front of me last week as he pulled away from a light. The smoke totally blacked out the windshield for 5 seconds while I was in motion. I was totally blinded by this.

I had no idea this was a thing, much less that it was something people did on purpose.

Had a car in front of me have a rapid deconstruction of the engine in front of me while driving down a motorway.

Driving into a ploom of steam and smoke, while also being hit with fragments was terrifying.

I wish they'd go back to just hanging plastic testicles from the trailer hitch, honestly.

Maybe they finally realized that they had been giving their trucks gender affirming care.

It's very much on purpose. To do it with a modern diesel truck you need to remove the DPF, and reprogram the ECU to run rich and to ignore the missing DPF.
