ADAS

Advanced Driver Assistance Systems are now in almost all cars. 
Because most vehicle accidents occur due to human error, ADAS provide electronic aids to help prevent these.

Seatbelts were arguably the first such system.  Nowadays, a computer monitor/controller helps the driver with safe speed, weather detection, grip, cornering power, sign recognition, navigation, audible warnings, spacing, impact protection, lane-keeping, pressure failures, parking, and even “bringing you in to land” if you become unconscious.

ADAS typically operates through a combination of sensors including ultrasonic, LIDAR (light detection and ranging) and RADAR, as well as mono and stereo cameras. The sensors may be in the bumpers, windscreen, mirrors, doors and even badges.

My car is typical, and has about 30 of these systems.  (When I learned to drive, dad's Volvo had only 1).  Having them should keep you safer, but KNOWING you have them might make you rely on them so concentrating less.  Remember, the key is in the name: ADAS are to assist you, not do the job for you ... or make the final decision!
