Really curious about this.

Two roads from point A to point B.

Road A is mostly highway where the distance is 50 km / 31 miles, speed limit is 120 kmph / 75 mph and the average speed is maintained at 100 kmph / 60 mph for higher fuel efficiency. The traffic allows maintaining that speed for the whole trip, cruise control option is on and changes in speed are rate and minimal.

Road B is through multiple settlements. Distance is 33 km / 20 miles. Where speed limit is 80 kmph / 50 mph outside city limits and 50 / 30 inside. No traffic lights, only roundabaouts. Average speed maintained is 40 kmph / 25 mph.

What would be the difference in fuel consumption for any car of your choice?

Because there are multiple narrative driven statements like how some US states have higher GDP than other countries (i.e. Mississippi) and how California GDP would be at the top of the world ranking even if independent from the States. A question popped up in my head.

How would they be impacted if they were indeed independent countries working outside of the frame that USA gives - access to labor, big market without import/export regulations and so on?

I understand it will for sure will be worse, but how much?

Thanks in advance for your answers.
