Are kill switches still a thing?
Yes, but a kill switch only works if you remember to do it.....
That's how my family got our first 400 series Burb. Our 84 square body Burb got stolen from the driveway. It had a keyed kill switch that Dad and I installed behind the grille. Long handle on the key, made a good weapon too. But he took my brother and I to our place from work, went back home, and came out the next morning to a pile of glass that used to be the vent window. Dashboard was partially disassembled ( Dad and I were working on it) but the truck was still drivable. But if he'd remembered the switch, maybe they'd have been slowed down, or caught.....
Oh well, it got me a good 99 Burb ( until it got wrecked) and then the one I have now. I miss my square trucks, but I like my current Burb too.
