ELI5: Why aren’t cars shaped like teardrops?

If teardrops are an extremely aerodynamic shape, why aren’t cars shaped like them?

Are modern car designs the most aerodynamically efficient they could possibly get? Or is there another reason why cars aren’t seeming to get more tear-shaped?

Cars need to balance aerodynamics with other considerations such as ease of manufacturing, cargo space, passenger space, curb appeal, etc. 

Modern car designs are certainly not the most aerodynamically efficient they could get. Ever seen a Toyota FJ Cruiser? Or basically any Jeep?
