Charles Manson's VW Bus

Origin
Charles Manson was a musician and criminal who led the Manson Family, a group in California with murderous intentions. He convinced the group to commit seven murders in his belief that they would help begin an apocalyptic race war, which he took from the Beatles song ‘Helter Skelter’ and wrote his own version. His death sentence for joint responsibility of the crime was commuted to life imprisonment in the state of California.

Effects
Known to self-activate, anyone who inhales its exhaust fumes is compelled to drive the bus, and will run down anyone they consider inferior. The ultimate goal of the bus is assumed to be to cause as much chaos as possible. When running, the radio automatically plays 'Helter Skelter' on loop and cannot be shut off. The only known way to neutralize it is to get it to crash severely enough to render it undrivable, though the driver may not survive. The bus will repair itself over time, making decommission by destruction unfeasible and requiring total lockdown.
