What cars have automatic turn signals?

Currently, models equipped with the automatic turn signal function mainly include high-end models such as Tesla Model S/X/3/Y, Mercedes-Benz EQS/S-Class, and BMW iX/7 Series. Some models also feature blind spot monitoring linkage functionality, extending turn signal flashing duration when a safe lane change isn't completed. Automatic turn signal technology is typically integrated into intelligent driving systems, triggering when the steering wheel is turned beyond 5 degrees or maintained for 2 seconds. In standard mode, signals flash 3-5 times before automatically deactivating. During rainy or foggy conditions, brightness increases by 30% and flashing frequency rises to 2Hz for enhanced visibility. Notably, certain local market models like the Proton X90 now offer basic automatic turn signals activated by steering angle without environmental perception integration. Prospective buyers should verify the system's response logic through test drives to ensure it meets their requirements.
