The body and the chassis are really the only parts that need to be built for the sake of breaking for safety. The other parts on the car do not need to be disposable, but for the most they are. The part placement and design are not engineered with repair in mind.
5 Years… This is part of the problem… What happens to this car after 5 years, it gets “recycled”. The metal does and the rest goes into a landfill to gas off. Micro plastics are just part of it, the gasses are a major polluter too. The reason you can own and keep your old car is that they were built to last, our current disposable society is the problem. Electric cars are dirty! Let go dig massive hole in the desert, lets separate the wanted materials out with lovely chemicals, then we can throw it all away. So clean… Right to repair, build to last, and strong public transport is the way to go.
A new car lasts for about 6 years, needs upkeep like an old car, and has little if any resale value. You then buy a new car, using more materials many that are plastic and cannot be recycled. Even a electric car is not green, the batteries alone are a mess, not really recyclable and made of non-renewable resources. New cars are not meant to be re-used and repaired they are disposable like everything else in our society. What we should have as an environmental goal should be a dynamic public transportation, right to repair, and end our disposable ways.
That’s not what I said, I said those were the parts of the car that really need to be crafted to break for safety. Your interior, electronics, your transmission, engine, etc. Can be designed with repair in mind like older cars. Most new cars are a pain to repair and not because they need to be.
