Nowadays the majority of car body parts are made of plastic, especially head and tail lights. Why is this?
Maybe it’s because plastic lasts longer than the ‘old-fashioned’ metal and glass. But it doesn’t. Or perhaps plastic car parts are cheaper. Actually it’s more expensive to replace a plastic car part than a metal or glass one. The people who save money by using plastic are the factories. Could this be why the majority of car body parts are plastic?
The fact that there is a majority of car body parts made of plastic in modern cars raises an interesting question: if our cars are made mainly of plastic, will they last long enough to one day be classic cars?
