Here is the car flamethrower:

The Blaster (also called the “BMW Flamethrower”) was a 1998 invention by South African inventor Charl Fourie designed to provide a defence against carjackings.
The invention came in response to the increasingly severe violent crime situation in South Africa, which in 1998 had already made the country (particularly Johannesburg) the per capita murder, assault, rape and carjacking capital of the world.[1] The Blaster was a liquefied petroleum gas flamethrower installed along the sides of the vehicle under the doors. Should a group of carjackers suddenly attack the vehicle while it is stopped in traffic (the typical scenario), the occupant could flip a switch and direct 5 metre plumes of flame upward into the facial area of anyone trying to enter the vehicle through the doors or windows.
Fourie claims it is unlikely to kill but would “definitely blind” the assailant. In South Africa, it is legal to use lethal force in self-defence if in fear of one’s life, and ownership of flamethrowers is unrestricted.
The Blaster received ample (and often satirical) media coverage from abroad. In particular, it earned its inventor the 1999 Ig Nobel Peace Prize (a parody of the real Nobel Prizes).
