Yeah, I'm not buying that argument. Everyone makes it sound like it will be this wave type event. But I'm pretty confident that autonomous cars will take decades to attain any sort of market saturation to influence insurance rates in that fashion. All you have to do is look at the history of transportation to see this.
But's that's not what I'm talking about. People will not give up their ability to drive willingly. Not in the city and certainly not in the rural areas. Even with supposed higher insurance rates, people will still want to control their own cars outside of the highway commute scenario. IMO, I see this as a Silicon Valley bubble. Inside the bubble there is an animosity towards commuting and driving in general. It keeps them from seeing that a majority of the country actually enjoy driving. I live here and I see it every day. There is huge desire here to eliminate drivers because....well drivers here SUUUUUUCK.
