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 Mustang Mach-E 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.
The Mustang Mach-E has a standard 360-Degree 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 Mustang Mach-E’s standard Cross Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and Cross Traffic Braking automatically engages the brakes to help avoid a collision. The Model 3 doesn’t offer a rear cross-path warning system.
The Mustang Mach-E has standard 911 Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions 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 Mustang Mach-E and the Model 3 have standard driver and passenger frontal airbags, front side-impact airbags, driver 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, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras and driver alert monitors.
