I clicked on this thread thinking it was about a VW Beetle powered by a jet engine made by Bombardier. I figured the car shoots acid out the back to foil pursuers, the way James Bond’s Aston Martin did using oil.
It’s actually a better arrangement for a spy, since driving around in an Aston Martin gets you noticed, which you don’t want to do as a spy. Driving a Beetle is much better cover, and, if you keep a flower in the Beetle’s built-in bud vase, your enemies will be guaranteed to underestimate you, giving you an even further advantage.
