Then one day I started to think about Google Car and I realized that the "killer app" for Google Car isn't as a car, it's as a truck. I agree it won't happen overnight, but it will happen. According to the U.S. Bureau of Labor Statistics, there are almost 800,000 big rig truck drivers at $40,000/yr in the US. (2012 data) Another 40,000 drive delivery trucks. Politics are the only thing that will save it. It's too large a cohort of workers. I look at the the NAFTA provisions for Mexican drivers to operate in the US that haven't been implemented as evidence that Congress will discourage their adoption. Also, what congressman wants to be on record of approving "Big Scary Robot Trucks" that accidentally drove over the Smith Family minivan killing both parents and Baby Smith too.
