For enhanced safety, the front and rear seat shoulder belts of the Lexus LC have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW M8 doesn’t offer pretensioners for its rear seat belts.
The LC has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the M8’s blind spot costs extra.
To help make backing out of a parking space safer, the LC has standard Rear Cross-Traffic Alert, helping the driver avoid collisions. BMW charges extra for Cross Traffic Warning on the M8.
Both the LC and the M8 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, rearview cameras and driver alert monitors.
