Features with dynamic engine ?

There is a major question for Toyota designers That why these intellectual people haven't given the SENSORS in the front bumper. Always keeping safety it's a priority then why not giving sensors on all sides of cars. Even on cheaper cars sensors are given on front and rear All designers in Toyota kindly think about it. And some extra features they can provide were. Automatic. Parking. Rain sensors. Automatic rear gate closing. And foot opening sensor for the rear gate. Features with dynamics engines will boost your sail for years more. Just rethink on ur beast to make it best.
