The World Health Organization (WHO) estimates the annual mortality associated with road accidents at 1.35 million at least. It is common knowledge that humans are themselves responsible for most such mishaps, by over-speeding, not keeping their eyes on the road, or talking on the phone while driving. This is why several countries in Europe and the two in North America are mandating the installation of advanced driver assistance systems (ADAS) that can aid the human drivers and reduce the likelihood of a road crash.

As per PS Intelligence, the increasing focus on making roads and vehicles safer will help in the growth of the automotive ultrasonic sensors market from $3,461.9 million in 2019 to $6,096.2 million in 2030, at a 5.1% CAGR between 2020 and 2030. 

In this regard, a lot of countries are taking initiatives to allow for the functioning of semi-autonomous vehicles and encourage research, development, and testing activities for fully autonomous vehicles, which are those with level 4 and 5 autonomy. For instance, the Directorate General of Traffic (DGT) of Spain has allowed the operation of cars with up to level 5 autonomy. Similarly, in 2017, 33 U.S. states implemented vehicle-autonomy-related legislations, followed by 15 more the next year. Apart from implementing legislations, governments are working with automakers and automotive technology vendors to get their transportation infrastructure ready, which would fuel the demand for automotive ultrasonic sensors.
