I always loved in Snowcrash the key antagonist drove around on a motorbike with a side car with a ex-soviet nuke wired to a heart beat monitor. Security companies spent their time not trying to stop him but trying to stop his numerous enemies from trying to kill him

Sure its going to be a bit of a fizzle when the tritium decays but still gonna make one hell of a hole in the road if someone dares to hit him.
