The plan of the experiments has been to inject the gas into the room in which the subject was seated and then to apply a number of driving tests which have been worked out by DeSilva. These tests include brake reaction, depth perception, the ability to see dim objects at the side of a bright light, the ability to perceive the approach or recession of objects, and accuracy of steering...
