The first combinations of advanced driver assistance features, now available in some 2016 vehicle models, offer semi-autonomous driving under specific circumstances. Cars will soon have the ability to cruise on freeways and safely navigate traffic jams with minimal driver input. As a result of increasing volumes and technology improvements, as well as cost reductions, it is now feasible to install the multiple sensors necessary for such capability. The industry consensus is that more comprehensive self-driving features will be brought to market by 2020. Such features will enable more complex automated driving, but still require some supervision by a competent driver. However, the obstacles to autonomous functionality are not all technological. While more testing is still needed to develop robustness, the biggest practical hurdles to clear before the rollout of self-driving vehicles to the public are related to liability, regulation, and legislation. In the long term, though, autonomous vehicle technology has the potential to institute major change in personal mobility, particularly in large cities. According to Navigant Research, 85 million autonomous-capable vehicles are expected to be sold annually around the world by 2035. This Navigant Research report provides a detailed examination of the emerging market for different levels of fully and semi-autonomous driving. The study provides a discussion of the potential benefits, demand drivers, inhibitors, and technology issues related to advanced driver assistance systems (ADAS) and autonomous vehicles, as well as profiles of the leading vehicle manufacturers and suppliers. Global market forecasts by region for volumes of vehicles with Level 2, 3, and 4 autonomy, along with the associated revenue, extend through 2035. The report also includes an assessment of how quickly the percentage of vehicles with some autonomous capability will grow within the overall parc of vehicles on the road in each of the six major world regions.
