That what i have noticed as well and they keep it rather simple and limited which is good, almost fool proof. kind of like what apple does with its products.
I like MB engine , I still drive my '96 E-320 , but its electronic sucks... The good thing is that back then there were not many electronic devices like cars today,,,, and the more advanced techno in cars the more reliable Japanese cars are... Yes I help build computer chips so I know how important "electronic connections' are. VW is the worse in this category
