It depends on which time you exactly mean:
Early 1900's: A car was a rarity and only for the rich
1920's: Stock Market Collapse meant cars were even more unaffordable
1930's: More and more people get cars ( but still only for wealthy )
1940's: WW2 meant prices of metals went up; cars were unaffordable
1950's: The Golden Era in America. People were living the Dream and had cars, TV's and other luxuries.
I think cars have always normally had four wheels.
most people in the olden days
There are too many people to count that have cars now. Out of 100 people, 95 would most likely have cars.
Depends what you mean by "old stuff". In general, yes, they do. There are many organisations and businesses that make products the way we used to in "olden times". Such as shoes, vases, cars, books and so on. Your question is really to broad to answer properly.
More people don't have cars than those that have multiple cars. As for a hard number it would be a guess.
all the people in Jamaica that own cars
There are 3 bumper cars. Each car holds 2 people. How many people altogether?
There are many cars on the roads right now because people invent and invent more cars and then they make them. In the past people didn't have the much material to build cars. Now people are equipped.
210 million people drive cars in America
Ford Model T and Mercedes-Benz Limousines, Rolls Royce, Renault, Porsche (electric!), Stanley Steamer (driven with steam) and many more.
I THINK it was because England conquered most of the world in the olden times.
There are 525 cars for every 1,000 people in England.
