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.

Specific to the teardrop (and the extent of aerodynamics I know) with respect to cars, you’re not looking at just moving through the air with minimum drag — that’s not the optimization problem here, nor is it the optimization for planes and trains. Consumer cars need traction at all angles, and in many/most designs (and sadly for engineers and environmentalists) they need wheels with enough ground clearance to go over potholes and bumps, and worst of all they want protruding side mirrors (instead of more recent camera-only options). This gives rise to [unique aerodynamics optimizations](https://en.wikipedia.org/wiki/Automotive_aerodynamics) — the flat bottom being sealed so that air is redirected strategically to minimize drag in certain parts, maximize pressure in others, etc.. I’d say the abrupt, sharp cutoff to the back is the most counterintuitive part of car design imo, but that is apparently what produces the least drag for the overall shape.
Anywho, this is why I keep my cows spherical.

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.

The Mercedes EQS is the most aerodynamic production car in the world. Kinda looks like a future prius tho
Mainly because we, as humans, need to SEE out of the car. And most cars have the engine in front (as that’s better for cargo.)
Because of these two things, we often get the “reverse teardrop.”
