If the shape with the least air-resistance is a raindrop 💧, why are most cars shaped like a backwards raindrop? 🚗

Question

I am basing my question off this [image](https://study.com/cimages/multimages/16/dragcoefficients8851096396303799158.png)

Edit: Okay, okay, I should have said “teardrop” instead of “raindrop.” Talking about the *actual* shape of raindrops doesn’t really help given the visuals I provided.

Answer 1

Another option which has been considered: a teardrop shape cut off at the back, and actively compressing and ducting air from ahead and under the vehicle into the negative pressure zone at the rear. The study showed the aerodynamic gain was better than the energy needed to move the air.
