Driving down the expressway in our old beater one dominant feature was controlling my speed; not only how fast, but how consistent. That was the noise coming out of the muffler. It brought to mind this article I had read in the past about cars with emotions and the growing interest in ambient light fixtures.
How much energy is wasted with inefficient driving? How much stress or frustration is added to our daily lives getting angry at poor or aggressive driving? Computer software combined with GPS technology could use all the above features to create safer and more pleasant roadways. A color based speedometer conveying rate of travel without the need to divert ones eyes from the road. Ambient lighting and noise along with emotional expression can assess ones driving for all to see and hear, especially the driver, easing ones urge to inflict ones own form of judgment and adding to the problem. Drunk drivers could be known to all and discourage similar hazardous driving.
All too Big Brother? (not to confuse authors) "You say that I am mad?" Driving is a privilege, not a right. More important than fuel consumption lives can be saved.
