What does BSD mean in a car?

[SanRachel]

BSD in a car refers to the Blind Spot Detection system, which uses digital infrared cameras installed in the car's door mirrors to monitor the traffic on both sides of the vehicle, allowing for safer driving. This monitoring system alerts the driver through sound and lights when a vehicle approaches or is in the blind spot. The Blind Spot Detection system is particularly useful when changing lanes, reversing out of a parking space, driving in rainy or foggy conditions with obscured mirrors, or when driving at night with glare from headlights behind. Especially during rainy weather and nighttime driving, when the effectiveness of the rearview mirrors is reduced, the risk of traffic accidents increases significantly. Without a Blind Spot Detection system, determining whether there is a vehicle in the blind spot relies entirely on the driver's habits and experience, introducing a high degree of uncertainty and compromising driving safety.
