Cops can't see your engine from outside. The Prairie Cat is a known diesel burner, so they'll pull you over anyway. THEN you can explain that you're burning alcohol... and these aren't the drones you are looking for...

"Hello Officer Runs-Like-Snake." "Visa, License and registration, this vehicle does not fit emissions standards of the NAN and..." "Oh, this is not a stock vehicle, I have a Multifuel Engine that I got from Little Wigwam's Garage in Vancouver." "Oh, really?" "Yes, here's my visa, license, registration, receipt from the garage..." "Mind if I take a look at the rest of the vehicle?" "Go ahead, but Tony back there has been eating beans all week and..." "Tony?" "Yes, Tony, he's a resident of the AMC, he's checking out his other side of the family's native land." "Ah, mind if he, um, comes out to talk?"
*Over CommLink* "Tony, this does not forgive you for binging on the beans and franks!" "But I loves da real Beaners and Franks! Wes can only get them cheap enough here in the NAN."
