It’s common knowledge that biking down the everest will kill you. Why do so many people think 1 billion bikes won’t destroy our mountains?
OP, banning cars over 5000lbs will quickly bring you back to the medieval age. Your supermarket will only have 2 types of bread, from the 2 closest bakeries. There will be no meats or vegetables other than what your neighbors are planting. You will wear clothes made from the wool of the sheep you’re raising, because there’s no fucking way in hell anyone will get cotton from point A where it’s being farmed to point B where it’s being processed to point C where it’s being made into clothes to point D where it’s sold to you, not without a car. Your economy would shit itself and implode within days. Stock market would crash and depression would follow.
But yeah, sure, just ban cars over 5000lbs. What can go wrong?
Dumbass.
