IEEE Says That 75% Of Vehicles Will Be Autonomous By 2040

Earlier this month, the Institute of Electrical and Electronics Engineers (IEEE) boldly announced that its members had “selected autonomous vehicles as the most promising form of intelligent transportation, anticipating that they will account for up to 75 percent of cars on the road by the year 2040″.
Which raises a very serious question: are these guys nuts, or are they on to something?
