Check Out Toyota Sai’s New Safety Features [Video]
The most notable one is the Pre-Collision System that scans the road ahead of the vehicle and warns the driver when he is approaching another vehicle too fast. The system also prepares the vehicle for impact by tensioning the seatbelts and lessening the brake pedal effort for the driver. It even apply the brakes if the driver is not paying attention.
But it looks like the Pre-Collision System on the Sai does more than that. It scans the road behind the vehicle and turns the hazard lights on if a vehicle approaches too much. If the rear vehicle is not stopping and an imminent impact is predicted, the system prepares the headrests to absorb the passengers’ head impact with it and prevent whiplashing.
