Our cities and suburbs would be far more crowded if vehicles did not exist. Instead of rows of rows of single-family residences, most neighborhoods would be built up of tall apartment complexes. Assuming trains were still invented, most cities would have some kind of metropolitan rail network.
Cars have made it possible for most people to live in suburbs instead of urban centers, which means that they don't see or interact with each other very much. This could be fixed by having better transportation systems, but also just through social innovation - imagine if small communities were created where everyone knew every resident's name!
Suburbs are often seen as a safe place for families to live, but this view is completely wrong - most deaths in the US occur in suburban areas. If we lived in dense cities, then there would be more interaction between people and less space for violence to happen.
The noise and pollution cars cause goes unmentioned, but these are important factors too.
There would be many other changes too - for example, there would be no more need for oil refineries because there are no longer any cars on the road. Oil companies have found ways around this problem by turning their attention to alternative energy sources, but it shows how revolutionary cars actually are.
The world would be a very different place if vehicles did not exist. The absence of automobiles would have an impact on transportation, the economy, health, cultural development, and the environment. If we didn't have vehicles, transportation would suffer severely. There would be no way to transport large quantities of people or goods quickly, which means that commerce and society would experience major changes.
Without cars, how would you get around? Many people would stay in town because there's no need to worry about car repairs or finding parking spaces. Cities could develop their centers and expand outwards instead of sprawling out as soon as they reach capacity. Traffic lights and street signs could be removed since nobody is driving down the roads, and police officers can focus on crime instead of writing traffic tickets.
In terms of the economy, removing cars from the equation would mean less consumption of energy and resources. There would be fewer factories producing vehicles too, so this would also help reduce our impact on the environment.
Cars are important for healthcare too. Without them, many people cannot get to work, go shopping, or visit relatives all over the country. This means that medical facilities will need to be set up in other ways, like by building more hospitals or using alternative methods of healing such as acupuncture and massage.
Finally, cars affect culture.
Until the early 1900s, most individuals did not reside more than a few miles from where they grew up. It came down to personal preference and practicality. Moving just a little distance away used to take hours of buggy riding on rocky roads. Suburbanization would not have been conceivable without the vehicle.
Before cars, people lived in neighborhoods with easy access to local shops and restaurants. They went about their daily lives without having to travel far or use public transportation. In fact, most people didn't even own a car; they were too expensive for most families. The rich could afford to hire drivers, but most people had no choice but to walk or ride a horse.
Cars have changed many things about how we live today. Most people now have to travel long distances every day just to get to work or school. This requires an automobile which is why most households now have one or more cars in their parking lot. Suburbs are growing faster than ever before because of the ease of driving between houses in communities everywhere. Cars have made society dependent on oil which has caused many problems with our environment.
There are many other differences between then and now that result from the use of cars.
