You are comparing life functions with private car usage. Read the previous sentence again. That's what dependency is. People who have a dependency on something feel that their dependency is a need. You won't die because you don't use a car. If anything, using your car tends to lead to a bunch of negative health outcomes for you and a bunch of negative health outcomes for your neighbours. Do you imagine people smoking and blowing the smoke on your face everyday because they feel that they need to smoke as much as you need to eat or sleep? That's what dependency is. Eating and sleeping are needs. Gambling regularly, smoking regularly or using your car regularly is more of a dependency. I am not telling you to stop using your car but that you use it when you NEED it. And if you are needing it too much, just like the person smoking or the person drinking too much, you should evaluate your decisions. Every time you use a car you chip your health a little bit and everyone's health a little bit. Visualise it.
