For enhanced safety, the front and rear seat shoulder belts of the Lexus RZ 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 Volkswagen ID.BUZZ doesn’t offer pretensioners for its second-row seat belts.
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 RZ are reminded to check the back seat if they opened the rear door before starting out. The ID.BUZZ doesn’t offer a back seat reminder.
The Lexus RZ has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help 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 ID.BUZZ doesn’t offer knee airbags.
With its standard Pre-Collision System with Pedestrian Detection, the Lexus RZ is better at preventing collisions with pedestrians than the Volkswagen ID.BUZZ, according to the Insurance Institute for Highway Safety:

The Lexus RZ’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Volkswagen ID.BUZZ does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
Both the RZ and the ID.BUZZ 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 available around view monitors.
