What goes on inside an automaker’s research and development department is top secret but patent filings help shed some light on what we can expect to see in the future. Most of these outline ways to make cars safer, cleaner, or both but there are some oddball features that never see the light of day and for good reason… For instance, do we need a car with a tear gas dispenser and retractable telescopic tail? Toyota thought so back in 2012. It seems the Japanese giant had watched too many James Bond movies if it really thought it could add tear gas on its models or a telescopic 'tail' to improve aerodynamics? Hmm, just imagine a Land Cruiser with that on the back… But the idea by an engineer named Peter W. Ripley for a wind turbine system mounted on the roof in search for alternative automotive energy may have some legs in it.
