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 Countryman SE are reminded to check the back seat if they opened the rear door before starting out. The Mirai doesn’t offer a back seat reminder.
The Countryman SE has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Mirai doesn’t offer all-wheel drive.
When descending a steep, off-road slope, the Countryman SE’s standard Hill Descent Control allows you to creep down safely. The Mirai doesn’t offer Hill Descent Control.
To help make backing out of a parking space safer, the Countryman SE has standard Cross Traffic Warning with Brake Intervention, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Parking Support Brake costs extra on the Mirai.
Both the Countryman SE and the Mirai have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, rear cross-path warning, driver alert monitors and available around view monitors.
