New smart car feature alerts when you forget something in the back seat

It is okay to forget a bag of veggies in your car's back seat and not realising until the next morning. But it is certainly preposterous to forget your baby there.

To remind careless drivers to pick their stuff from the back seat of the car, Nissan has invented a new smart alert system called RDA or rear door alert that triggers the horn and gives a visual reminder message, Mashable reported.

Nissan plans to integrate the RDA system to its 2019 models for eight cars initially, followed by all four-door trucks, sedans, and SUVs by 2022.
