Yeah, the story contains some obvious bullshit. There is no way in hell a flashlamp-pumped Nd:YAG laser could cut through a piece of steel. With typical ~Hz repetition rate and ~J pulse energy, the average power is only around 1 W. This is three to five orders of magnitude lower than typical welding lasers. This could burn some paint or engrave metal, but burning through a wheel well and brake line is completely ridiculous.

He didn't claim it cut through steel, JGCs have polymer wheel wells and brake lines like most modern cars.

Maybe they meant the plastic wheel well liner? I don’t know if that makes sense, I’m just googling around looking at Jeep Cherokee images.

It's just there for flair. :)
