It's part of a larger agenda. It's not really about the cars it's about getting people to move to big cities and ride share.

This is where they first started testing these cars, navigating curves and other things is the easy part. Dealing with other traffic in congested are is where it gets difficult.

Repairing AVs is going to be completely beyond 95% of existing service options,

They will have to up their game if they want business. My Friend owns a small engine repair shop and is a dealer for major chainsaw brand. He sold this $2K saw to this guy and something was wrong with it. What he wasn't aware of when he sold it is there was electronics on it that require expensive diagnostic tools. The reason for the electronics is fuel efficiency, a saw a like this will eat gas even when adjusted well. He can fix engines but is clueless with computers.

As this technology develops every car will be collecting this data. Some car across the globe could know there is a pot hole in front of your house.

These cars use GPS primarily so they know where they are at, it's not required to navigate the car down a street. The primary navigation is with LIDAR and video recognition technology. Redundant mapping data will take care of any issue in case of GPS failure.

Artificial intelligence, the key word being intelligence. I realize this may be difficult to understand for many people but this is the best explanation I have. A ten year kid can identify the letter A in many different fonts despite the fact they never saw it displayed in that font before. This requires intelligence.


A conventional computer is nothing more than a glorified calculator but crunching numbers is something it does extremely well. It's limitations however become quite evident when it needs to identify an A. You need to feed it an example of an A in every font for it to identify it as an A. If it has an example it will be right every time, if it has no example it will not be able to identify it.



With a computer using AI technology you give it 50 examples of the letter A and then teach it to identify the rest of them. What's important to understand is it can be wrong just like humans and like a human it learns from it's mistakes. It doesn't file away an example of the A that was a mistake, it adjusts the logic that made it arrive at the wrong answer. The longer it operates the more intelligent it gets. Identifying a letter A with AI may sound simplistic but it's not. Back in the 50's they thought they would be able to do this easily but quickly learned they were wrong. The human brain is really complex and replicating it is not that easy, however the current technology is rapidly advancing. When you combine that AI technology with the immense computational power of a computer it's something humans will have difficulty competing with in the not so distant future.


Getting back to the cars they are identifying problems that they have never seen before and making decisions on their own. You don't need a line on the side of the road or some kind of guidance because it identifies the road itself.

That's not going to happen. Once they perfect this technology and it's more acceptable to the public it might 10, 15 years or whatever from now. They will then mandate it in all new cars but you will still be able to manually drive it. Another 15 or 20 years down the road there most cars on the road will be capable of driving themselves and that is when the switch will occur. It might be 30 or 40 years before all cars are driving themselves, it's not a matter of the technology but practicality.

They know this Harry, spooky huh? To retiterate the GPS is not used to drive the car itslef althugh it could be in the future. The primary driving of these cars is done with LIDAR and video recognition technology. It can "see" like you do and with 360 degree sensors at multiple heights better than you can.

You could just have the option of answering emails or reading a book in the car on your commute now.

Perhaps a virtual helmet and you can pretend to drive the car.

This tech will actually have the opposite affect. People that cannot have personal vehicle now like blind person for example will be able to own a car. This tech will not limit options, it will expand them.

The AV will locate with a set of sensors. These will include GPS, LIDAR, Inertial, Video. The combination of GPS and the others will provide centimeter level location even in snow storms. It is slimply not a hard problem.

And we will swiftly get to communicating vehicles. Probably should do this for all. The retro would be cheap to existing vehicles.

The fun problems will be the soft ones. I am still of the opinion that the AVs will all be knocked linitially for lack of balls. Too hesitant and tentative in things like left turns and four way stops.

I believe however the end of the human driver will occur rather swiftly...and it will be driven by the insurance companies. If the AVs have a third or a quarter of the accident rate the differential is going to drive it.
