Why cars are so ugly now??

A major factor, in my opinion, is safety regulations, which require cars to be wider and have softer front ends to reduce harm to pedestrians. Also, mass production seems to favour more uniform and 'boring' designs with fewer unique elements, and many companies, I think, are trying to achieve a futuristic, minimalist aesthetic, aiming for a 'spaceship' look. 

Also its because car companies try to apeal to more wider audience, so they change the look of a car to be more pleasent to day to day life. (For example look up evolution of Mitsubishi Eclipse)
