Hippy Car
A "hippy car" specifically refers to the original Volkswagen Type 2 Transporter, more commonly known as the Volkswagen "Bus".
In the TV series "Lost", Hurley found one left over from the Dharma Initiative, and upon seeing it, James "Sawyer" Ford said "I'll be damned, you all found yourself a hippy car."
hippie car crash
A car/bicycle encounter when the driver of a parked car exits the vehicle only to see a Birkenstock wearing burlap bag carrying hippie driving an old 50's style bike heading toward the open door. The hippie cannot access the bike's shitty brakes due to the wearing of sandals resulting in the hippie swerving to avoid the open car door, loosing control of the bike and then crashing on the roadway.
Some dirty old, bike driv'n hippie almost hit me while I was getting outta my car. Fucking bum couldn't even work the bike brakes which made him go flying off the bike and crash'n himself onto the pavement causing a hippie car crash. He Musta been high on that old style weed.
