When I watch the AV's out on the road, two things come to mind. First is the space shuttle and all of the billions of dollars of research and the redundant safety systems. I seem to recall that not one of the first 100 space shuttle flights launched as scheduled. I remember visiting the launch site to see one go up and then was told a computer program shut down the launch with less than a minute on the clock. Not to mention two of the flights that ended in explosion and disintegration during re-entry. My point being, NASA can request another few billion dollars to fix the problem and try again. When AV's take out a family, the lawyers will come from far and wide to cash in. How deep are the pockets of AV makers?
The second thing that crossed my mind was what I see each and every day living and driving in a big city. Aggressive drivers. If you are driving a mere 10mph over the posted limit, they will run you off the road. Every morning we watch the news to see where all the crashes are and what parts of the interstate are backed up. I'm guessing it's that 25% of drivers that are compulsive speeders, who cut in and out of traffic. They even drive like that on Sundays. They can't help themselves. The most noticeable are the men in their lifted 4x4 trucks. Part of that macho look is driving around everyone else, no matter if it is rush hour. these types of people will not get into an AV if it drives the speed limit. Not ever. They would rather drive uninsured than drive the speed limit. It is a lifestyle choice for them. The AV's will one day be met with a hail of gun fire from these angry drivers.
I have not read a lot about AV's just yet. I try to picture them on snow and ice and driving through thunderstorms, and reacting to blow-outs or being side-swiped by another vehicle. I really believe lawyers are going to make a comfortable living filing lawsuits against owners and makers of AV's when things don't go as planned.
