I don ' t know if you realize this , but a lot of supercars and luxury cars are built beforehand to pass down technology to economy cars . Someone has to pay for testing new technology . New technology isn ' t exactly cheap and what better way to experiment with tech , is with people who have money . It ' s not like they are building cars just for the heck of it . A lot of the design features in today ' s supercars will most likely be implemented to more affordable cars in the future . I ' m not a big fan of Tesla personally , but Tesla for example started with their most expensive models for RND and are now trying to make more affordable all electric cars . I still wouldn ' t consider the model 3 affordable to the average car buyer , but it ' s certainly more affordable than the model S or X . The same can also be said on any platform of technology . Especially computer parts and phone parts . Monitorsscreens , GPUs , CPUs , etc .
