Thou shalt not drive all the way to the end of the closed lane before cutting in front of meek who have patiently been waiting in the open lane (otherwise the vengeance of Meek will be upon you when they inherit the earth)
If you think about it, “Thy horsepower shaly not exceed thy I.Q.” covers everything - most people won’t even have cars, and the ones who do will probably not commit idiocies with them. As blissful a vision as this may be, I’ll submit my own Commandment: “Thou shalt respect thine fellow travelers, especially the ones on bicycles, dammit!”
Thou shall not linger longer than 10 seconds at a green light, lest the impatient schnook who’s late for work sound his horn
Thou shall delay 10 seconds before sounding thy horn at the driver lingering at a green light, lest ye frighten the malingerer and cause him to delay another 10 seconds
Thou shalt not refer metephorically to your secret purchase of a 1969 Citroen DS-21 Pallas with hydro-pnuematic suspension and swiveling headlights as “taking on a 38 year old French mistress”, lest your wife misinterpret the recent transfer of funds from your bank to an overseas account, and thereby disturbing domestic tranquility.
Thou shall not tailgate people who are already going above the speed limit, especially if you’re near a speed trap.
Thou shall take thy turn at 4 way stop signs.
Thou shall not take advantage of good drivers by pulling in right ahead of them, unless you’ve already been waiting for 10 minutes, and there’s no other chance for you to get out but to do that. Especially thou shall not cut in front of a driver when there’s nothing but space for miles behind them.
Can we have some rules for bicyclists, too? Like “Wear your helmet if you have a working brain and want to keep it that way” or “Do not ride your bike in the middle of the road, especially a one-lane road.”
