In the annals of “whatever happened to that big idea” is the 2009 announcement of road trains linking cars in a convoy, a scheme planned for Europe’s motorways. The lead vehicle would have the active driver and the rest of the cars in the convoy would be autonomously driven. Someone, possibly with a sense of humor, dubbed the undertaking as the Sartre Project, standing for Safe Road Trains for the Environment. This month comes the report that the idea has been successfully tested and is a step forward in a plan to change the way vehicles travel.
