There have been a few spoofs about that chdot has mentioned, so how about...
The Vanilla Ice Way Code
"Alright stop, collaborate and listen" seems like a pretty good opening gambit...
The Price Way Code
An alternative motorist lead code that allows you to use the roads if you pay for them. The natural extension is a relaunch of 'Road' tax, and people with bigger cars who pay more such tax get their own special lanes.
The Miami Vice Way Code
Socks are banned, plimsolls encouraged, and any sleeves must be rolled up. Sunglasses and Hai Karate obligatory.
The Spice Way Code
Peppering road users with advice, such as 'give cyclists mace', and asking drivers not to cumin the bike lane. Aimed at spreading the clove.
The Splice Way Code
Separates road users.
The Dice Way Code
Meh, we're changing nothing, take your chances.
The Mice Way Code
Very similar to the Nice Way Code except drivers are encouraged to treat cyclists like rodent vermin. So pretty much identical in all respects to the Nice Way Code really.
