Or maybe they're just driving on the streets with an FXX race car and taunting the cops, as seen in the video here.
The fine folks at edo competition say that with a few add-ons they've manage to obey all the laws for a street-worthy vehicle in Germany. A proper windshield, all the required lighting, hand brake, and an exhaust system that makes the FXX meet all emissions standards. A new suspension has also been added with damping and adjustable compression.
No mention of bumpers, though, which one would think would be the first thing you'd need to make a race car street legal. Otherwise, scraping a cement pillar at the local shopping mall with your new FXX may become an expensive lesson in obeying the law.
