The Grand Wagoneer L’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The R1S doesn’t offer pre-crash pretensioners.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Grand Wagoneer L are reminded to check the back seat if they opened the rear door before starting out. The R1S doesn’t offer a back seat reminder.
The Grand Wagoneer L has standard Active Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Headrests system moves the headrests forward to prevent neck and spine injuries. The R1S doesn’t offer a whiplash protection system.
With its standard Full-Speed Forward Collision Warning Plus, the Jeep Grand Wagoneer L is better at preventing collisions with pedestrians than the Rivian R1S, according to the Insurance Institute for Highway Safety:

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Jeep Grand Wagoneer L achieved a “Acceptable” rating - the second highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Rivian R1S has not been tested.
Over 200 people are killed each year when backed over by motor vehicles. The Grand Wagoneer L has standard Park Assist with Rear Stop that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The R1S doesn’t offer backup collision prevention brakes.
When descending a steep, off-road slope, the Grand Wagoneer L’s optional Hill Descent Control allows you to creep down safely. The R1S doesn’t offer Hill Descent Control.
The Jeep Grand Wagoneer L’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Rivian R1S does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
Both the Grand Wagoneer L and the R1S have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, driver alert monitors, available all wheel drive and around view monitors.
