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 bZ4X are reminded to check the back seat if they opened the rear door before starting out. The Model 3 doesn’t offer a back seat reminder.
When descending a steep, off-road slope, the bZ4X AWD’s standard Downhill Assist Control allows you to creep down safely. The Model 3 doesn’t offer Downhill Assist Control.
The bZ4X Limited has a standard Bird’s Eye View Camera to allow the driver to see objects all around the vehicle on a screen. The Model 3 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
To help make backing out of a parking space safer, the bZ4X’s standard rear cross-path warning system uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Model 3 doesn’t offer a rear cross-path warning system.
The bZ4X has standard Safety Connect™, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Model 3 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the bZ4X and the Model 3 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, 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, blind spot warning systems, rearview cameras and driver alert monitors.
