The Blind Spot Monitoring (BSM) system can indeed be retrofitted to vehicles to enhance safety. The market currently offers various solutions, including standalone kits utilizing 77GHz millimeter-wave radar technology, priced from approximately 1,500 to 6,000 Malaysian Ringgit, depending on the system type and installation complexity. These systems typically feature a 70-meter detection range, alerting drivers to vehicles in blind spots through rearview mirror indicators and audio-visual warnings, while supporting non-invasive installation to maintain the original vehicle structure. For instance, the dedicated BSM retrofit kit for models like the Toyota Land Cruiser Prado employs a dual-sensor design while preserving the OEM mirror appearance, with installation requiring approximately 2.5 hours. Notably, new vehicles such as the 2024 Isuzu D-MAX now come standard with an ADAS system incorporating blind spot detection, utilizing stereoscopic camera technology to achieve a 150-meter detection range. It must be emphasized that this system serves as an assistive feature, and drivers must always verify conditions using their rearview mirrors before making manoeuvres.
