It would also make it much easier for corporations to exploit authors.

They would generally make most of their money early (in the couple of years following when the content is released). Individual authors would be much more affected, it might take years for your book to become popular. Also imagine if a studio decides to make a movie or tv show just right after your copyright expires, they wouldn't pay the author anything and just have higher profit margins.

Patented inventions and technologies have some sort of direct practical value. Society does not really benefit much if anyone is allowed to created derived works based on any copyrighted content without compensating the author.

I don't think cars are copyrighted unless you want to make an exact copy of it you shouldn't run into any issues.
