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 Tundra are reminded to check the back seat if they opened the rear door before starting out. The R1T doesn’t offer a back seat reminder.
The Tundra has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The R1T doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Over 200 people are killed each year when backed over by motor vehicles. The Tundra offers optional Parking Support Brake that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The R1T doesn’t offer backup collision prevention brakes.
Both the Tundra and the R1T 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, lane departure warning systems, rearview cameras, available four-wheel drive, blind spot warning systems, rear parking sensors and rear cross-path warning.
