“With television the image we have of our bodies is profoundly altered by the fact that the image goes inside us, and this has had a profound effect on the motorcar. The safety car is partly the response—that or the effect—of television on the motorcar. Involvement in the motorcar in a new way makes people feel that it’s something they ought to be able to control and in which—from which—they might expect a certain degree of safety. This is very much a TV effect on motorcar—it may destroy the motorcar.”

— Marshall McLuhan
