For enhanced safety, the front and rear seat shoulder belts of the Lexus ES 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 Honda Insight doesn’t offer pretensioners for its rear seat belts.
The Lexus ES has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Insight doesn’t offer knee airbags.
The ES has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Insight doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Over 200 people are killed each year when backed over by motor vehicles. The ES offers optional Intuitive Parking Assist with Auto Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Insight doesn’t offer backup collision prevention brakes.
The ES 250 AWD has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Insight doesn’t offer all-wheel drive.
The ES offers an optional Panoramic View Camera to allow the driver to see objects all around the vehicle on a screen. The Insight only offers a rear monitor.
Both the ES and the Insight have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.
The Lexus ES weighs 612 to 780 pounds more than the Honda Insight. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Lexus ES is safer than the Honda Insight:

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, and daytime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the ES the rating of “Top Safety Pick” for 2023, a rating granted to only 53 vehicles tested by the IIHS. The Insight has not been fully tested, yet.
