Before the automobile, hippies did not have anything to complain about other than fur and meat. It was obvious by this time that whining about fur and meat wasn't doing anything, so instead the hippies turned to drugs and playing bad acoustic guitar. It was the invention of the automobile that changed things. When automobiles became popular, hippies created a new hobby of making up lies about the ozone layer. Hippies also protested imported cars, and created the slogan 'Every time you buy an import, god kills a kitten'. The slogan can still be seen as a bumper sticker on cars today, but mostly just on imports with the intention to make the hippies angry.
