Since you mention cars and trucks separately, it seems you don't realize that trucks handle last-mile delivery of groceries in cities, after the goods are offloaded from trains (in normal countries). And that any decent-sized city would fall apart in a week tops without a constant supply of groceries.

I agree! Truck size are a reason lanes are so wide that enormous big vehicles like SUV are popular and even comfortable to use. Subcompact cars should be called a car. Two-seat cars should be called a compact car. And one-seat should be more popular and called Subcompact. B segment sedans should be called family car. SUV should be banned. You got the idea.

But, as others pointed out, I don't understand how busses as public transport should work. How grocery logistic should work. How firetrucks should work. In imaginary city I described. This is dilemma for me.

The hospital needs an mri machine? Here's a handcart, good luck!

I agree
