King for a day

1) No more CUVs permitted.  All SUVs will use body-on-frame construction only, and be offered with legitimate 4 wheel drive, a decent tow rating, and a V8 powertrain

2) All drivers education courses will teach the use of a manual transmission, and automatic transmission vehicles can only be driven if a waiver is issued by ye Royal DMV

3) 200TW tires will be offered in all available passenger car sizes by royal decree

4) Drivers who do not use their turn signal to indicate turns and lane changes will be beheaded, and their body quartered and buried in each of the 4 corners of the kingdom, as a warning to all. 

SO LET IT BE WRITTEN.  SO LET IT BE DONE.

You know, I gotta say that while I like a lot of these, implementing others would mean that we would lose out on a whole bunch of wonderful cars.

Everything gets lsd, everything (everything awd gets 3). 

Everything with less than 4 seats without a bed is mid engined.

Everything gets a manual transmission unless it's so ungodly fast that it Needs paddles  (like 700hp+?)

Every driver has to do the first 5 years on a motorcycle. (Bad drivers will sort themselves out). 

Some of you all are harsh royals indeed.  I'm not necessarily trying to turn the clock back, just level the playing field:
 

-Any drivetrain package that has been certified by an oem can have a manual transmission option added with no additional re-certification required.  Minor tuning (+/- 50%) to the ecu allowed to accomodate this.  Hello manual transmission widebody charger hellcats.  

-Manual transmission vehicles can be sold factory direct with no dealership involvement. 

-All safety testing (IIHS, DOT, etc) is done with belted passengers only.  No test modes that involve unbelted passengers allowed or considered.  Time for our performance seats to look more like europes (bolstered and less airbags), and for greenhouses to get big again.

-CAFE rules do not get a vehicle size adjustment.  

-Any OEM can build heritage or continuation versions of their old models and sell brand new. 

Option to purchase a "fun" version of high performance cars without a warranty for a much lower cost.

When I am king, any new road constructed or re-paved will have a bike lane included.

I like these two rules a lot.

My third rule would be if you consider a car simply a tool you get a electric car.

No one else is allowed private vehicles but me. All you peasants must walk, bike, or take public transportation. 

I figured since we are all throwing out improbable and silly rules I would too. 

Use it or lose-it rules: 1) Trucks have a way to measure payload and towing. If you haven't used your 3/4 ton truck to haul something heavy or tow something big in the last year you get to trade it in on a half ton, and then down to a compact. Your truck was meant to be used, so use it or lose it.

2) Cars that are in the top half of the performance envelope for new cars sold (as measured by 1/4 mile times) measure and record your throttle usage. If you've got a hellcat and you never use it you can trade it in on a charger with a pentastar. But I'll let you swap the badges so you still feel good about yourself. The car was meant to be used, so use it or lose it.

3) Public transit is free. Let people that don't care about driving just sit.

Dear god, I don't want to be anywhere near people who are forced to "use" their Hellcat on a public road.

Let 'em take it to the track then! Still counts as use.

You know you are all just trying to build this:

using the same technology as radar cruise control and lane departure warning, a system will be installed on the rear of each vehicle. Whenever it detects the driver is in the left lane camping with no traffic in front of them, the stereo starts blasting "MOVE B!TCH, GET OUT THE WAY"
