For your Supercalla game:
The Astrophalt Turf Hyper Stream (ATHS) works with the cops to keep traffic flowing safely. At least it does when it is functioning properly.
One of the tools of the PACT was to make it mandatory for all road vehicles to have a regulator... a device that regulates speed. With a properly installing regulator you won't be able to drive too fast and cause a nasty accident.
But maybe you don't want the PACT controlling your ride. Maybe you want the freedom of the ATHS atmo in your hair as you and your chopper drift along at speeds far greater than 55 GMPH. If that's the case, you need a fake-yulator.
The fake-yulator is a device that mimics a regulator, issuing the correct digital codes to fool cop radar and ATHS detectors. But it doesn't actually regulate jack.
If you are using a fake-yulator and the cops come sniffing around, roll 1d6. On a roll of 1, the device malfunctions and you are probably busted. On any other roll you're golden. Keep on truckin'.
The fake-yulator is not legal and so you'll have to pay in excess of 500 STDs in a pawn shop or seedy joint. Maybe more. And be aware that some fake-yulators are actually fake. They send a signal to the cops letting them know you're trying to fake 'em out. Since these are nearly indistinguishable from the real ones (they all look like real regulators, remember) you might not know when you get one. But the GM will let you know...
