Now days there are so many other things going on. There is the cell phone, on star, nav screens, GPS devices, reading all the info on the DIC, reading the head up display, text messaging, drinking a beverage, changing a CD or selecting a new song, tuning the satillite radio. Then there are all those other things that people have done for years before all the "techy" stuff came about. Thing like reading a magazine, reading a map, tending to a child, lighting a cig, adjusting the radio or the climate controls, setting the cruise control, turn signals, raiging or lowering a window, checking the guages. I have even seen people brushing their teeth, shaving (men only, but there probably are a few women that do), putting on makeup (women only, but we all know that there are men that do also).
Well, as you can see I could go on and on with all the things that people do in there cars now days. Yes, many of which should NOT be done, but yet they are. Oh yeah, forgot got one, keeping both hand on the wheel.
Even an Octopus would have a difficult time driving a car in today's world with all the gadgets and gizmos that are part of the car, an accessory to the car, or just things that we no longer have time to complete else where.
Oh, by the way. I do wave.
