Cars? Do we really need them? Yeah, people can argue that they make daily tasks much more convenient. But imagine life without personal cars. I think life would be much more convenient and simpler!
Cars account for approximately half of the greenhouse gasses emitted. They expand our lives to include all aspects of it to a larger area by multiple factors. Work can be over 30 miles away, as with grocery stores, friends, entertainment, etc. What if we went back to the times where everyone survived in their local community? People can ride bikes to their school. They can walk to the bank. The community is sustainable within itself instead of relying on large (inter)national companies or governments to support them. Our health would improve because we would need to walk or bike to the places we need to go. Much of our laziness is due to the convenience of technology. Being forced to exercise when you need to go somewhere would solve this problem. The communities across the country would be more sustainable– they would need to be able to survive on their own. No more communities would be able to survive in unsustainable regions like Las Vegas, where the arid climate cannot support the population they currently have. We would learn to survive on the local resources that the area you live in provides.
Life would be much simpler. Like in many other cultures around the world, people would become more important than keeping a schedule. Some countries tolerate lateness if you bump into a friend on a street and talk with them for a bit. Like Jim’s post addresses, we would appreciate life more with this type of lifestyle. No more stressing about getting somewhere on time. No racing through the streets and putting your life, and others, in danger to get somewhere on time. No stress to do so many things in one day because of the ease of traveling. Stress is very bad for your health; it decreases your life span according to WebMD. Many benefits would come with restricting personal cars. Although we could rattle off many negatives, people still had fun without them a century ago.
(The transition would be tough, but the end result would help many facets of life. Commercial transportation and minimal public transportation would still exist: planes, trains, boats)
