Active noise cancelling (ANC) is a software process that uses existing in-vehicle infotainment hardware to eliminate undesirable noise within the interior of a vehicle. This elimination technique is known as harmonic order reduction, where unwanted audio signals are identified by sensors and filtered out of the overall interior vehicle sound. [ 3 ]
The speed difference to allow an automatic stop was raised to 50 km/h (31 mph) in 2013 with improved cameras. [49] The adaptive cruise control was also upgraded in 2010 to allow automatic emergency braking in traffic, fully stopping the EyeSight vehicle when the car in front has come to a complete stop.
As a result of increased sales of full electric vehicle and hybrid electric vehicles in several countries, some members of the blind community have raised concerns about the noise reduction when those vehicles operate in all-electric mode, as blind people or the visually impaired consider the noise of combustion engines a helpful aid while crossing streets and think quiet hybrids could pose an ...

According to a 2020 Annual Review of Public Health review of the literature, self-driving cars "could increase some health risks (such as air pollution, noise, and sedentarism); however, if properly regulated, AVs will likely reduce morbidity and mortality from motor vehicle crashes and may help reshape cities to promote healthy urban environments."
In the 2016 Berlin truck attack, the vehicle used was brought to a stop by its automatic braking system. [39] Collision avoidance features are rapidly making their way into the new vehicle fleet. In a study of police-reported crashes, automatic emergency braking was found to reduce the incidence of rear-end crashes by 39 percent. [40]
Understeer occurs when the car's front wheels do not have enough traction to make the car turn and oversteer occurs when the car turns more than intended, causing the car to spin out. [37] In conjunction with other car safety technologies, such as anti-lock braking and traction control, the ESC can safely help drivers maintain control of the ...
