Lots of small speakers deliver bass that seems impressive for the size, but a combo of
tiny active drivers and a radiator can leave them with very obvious masses in the treble and bass, but a flawed bridge between the two.
Among them:
active cruise control to keep vehicles at a safe buffer distance from others at highway speeds; lane - change warning systems that use
tiny cameras and sensors to identify lane markings and warn
drivers when their vehicles start to stray; and emergency systems that automatically tighten seat belts and apply the brakes when a car is closing in dangerously fast on the vehicle in front of it.
