The copy for the car is " turn your ass to common sense / what is taken for granted".
Obviously the car's best sales point is its back design, and i guess toyota which is often perceived as the family friendly politically correct family car maker, wants to show that it can be edgy and be different from what people expect them to be.
So the sexy girl turning out to be a guy is a perfect way to show that off.
Does it sell the car or motivate me to buy it? No.
But i am very impressed at the risk toyota took.
