From what I’ve read a while back, there is a huge pressure on car makers to make their cars as streamlined and aerodynamic as possible to achieve their emission and efficiency numbers. The front of the cars look very similar now as a result of the focus on pedestrian safety and NCAP scores. The big door pillars protect against rollovers, and on top of that many of the designers moved from the big German car makes to the Koreans or even the Chinese brands. So yes I think these factors cause the cars to look very similar nowadays.
