Don’t forget things like pedestrian impact testing (which drove the front of the cars up), DOT regulations which require headlight/taillight positions, platform impact (shared chassis hardpoints to reduce costs), etc.
Not to say beautiful cars don’t exist, but the ability to think outside the box is pretty tough. Besides, these days everybody wants SUV’s so the investment into beautiful looking cars is more for nostalgia then profits at the moment. Porsche (a sports car company) sells 2 Macan/Cayennes for every 911/boxster/cayman.
