Toyota Safety Sense And Blind Spot Monitors

Impact on driving assistance features: It is essential to acknowledge that the presence of a BSM is not a substitute for performing proper visual checks, using mirrors, and indicating a lane change. While BSM can provide valuable assistance, it is important for drivers to remain vigilant and not solely rely on this technology.
