Autonomous vehicles are successful here and now but you are unlikely to meet one because the successes are in the upper atmosphere, open cast mines, nuclear power stations, underwater and in other relatively inaccessible places. As the new IDTechEx report "Autonomous Vehicles: Land, Water, Air 2015-2035" explains, the primary technology of an autonomous vehicle is that which confers autonomy and the powertrain, which is usually electric.These technologies by land, water and air have much in common as shown in figure 1 below. The powertrain and navigation and control technology of autonomous vehicles are rapidly evolving with every element likely to change radically and many merging; indeed it is already happening right through to structural electronics where the load-bearing bodywork doubles as electrical and electronic components and circuits. This is good news and bad news for autonomous vehicles. Good news in that functionality and affordability will improve but bad news in that long term testing is irrelevant when everything is frequently changing disruptively. What use is a five year test on a Radar when a Lidar replaces it? What to do with long term tests on a battery when it is replaced by one of the new lithium-ion capacitors? All this vast number of new innovations can bring initial lack of reliability and predictability with them yet if anything has to be superlatively reliable and predictable it is the autonomous vehicle operating near people. The more people are in close proximity, the greater the challenge. AVs are particularly lethal if flying over a crowd of people or navigating a crowded road with pedestrians crossings. From 2015-2025, most forms of autonomous vehicles are and will remain electric land and air vehicles. Electric powertrains are exceptionally controllable and they can directly activate and collaborate with other functions of the vehicle that are autonomously managed in coordination with steering and navigation. For example, an autonomous electric tractor will operate implements with great precision when they are electrically driven from the electric powertrain of the vehicle. This is invaluable in providing autonomy. In numbers and probably market value, the report finds most substantially-autonomous vehicles will be pure electric in number, notably robot vacuum cleaners at the order of one million yearly. However, if we consider minimally autonomous vehicles, then, from 2015 - 2025, the largest numbers and market value will include cars at the order of one million yearly averaged through the decade. The sales of cars with capability of self-driving through most or all of a journey on regular roads is estimated below. Paradise delayed. In the next ten years it will not be cars that are the great success. The sales of production cars with a capability of self-driving through most or all of a journey on regular roads are undergoing trials only in 2015 with some growth within the next five years to around 5000 worldwide by 2020. The following five years will see the initial growth spurt with Europe and North America seeing sales of around 300,000 each and half a million units delivered into East Asia. By 2030, East Asia will see sales of 10 million, growing to 22 million by 2035 with North America and Europe tailing significantly with between 5 and 8 million sales each in 2030 and 2035. The emphasis of the report is on lessons of success and failure and what comes next, with lead indicators of such success. Timelines to 2040 of market, technology and allied advances are given and detailed forecasts of sales of autonomous vehicles from 2015-2025 particularly concentrate on numbers, unit value and total market value.
