Small cars against older limousines

Evening… I am particularly interested in the developments in car crash safety. There are certainly some experts who know this topic well… I’m interested in some aspects: 1.) Crash tests Well, how can a customer know how safe his car is? Of course, he will look at the Ncap crash test. But I wonder how meaningful this test is. Generally, a dummy should be best modeled after a human being. But: The test runs according to a given pattern: Frontal with 64 km/h against a fixed and deformed barrier etc. Can you read everything. However, I wonder how often this situation occurs in everyday life… Also, some manufacturers of their cars should optimize so that they perform well. What do you say? 2.) The safety of new small cars compared to older ones, but larger After the NCAP test – whatever you think about it – many small cars are no longer inferior to the limousines. They are equipped with numerous active or passive safety features. What interests me: Can you say now: A new Renault mode, which creates 5 stars in the NCAP test, is safer than an S-Class from the 80s? Or a 7-series BMW? At least cars, which have already been paid attention to safety. Suppose it is an S-Kl asses with driver airbag (was available as an extra): 2.) Which one of the drivers is better off in a crash against a fixed obstacle? 3.) What does it look like in the frontal crash? So when the S-Class crashes together with the small car? The old Benz has certainly been designed quite differently in terms of safety. The car gives up so little – what I know. In addition, it has more sheet metal or more weight. So advantages in the frontal crash, I think. 4.) If the Benz or just the 7 B had MW NO airbag… How does the crash look like against a fixed obstacle compared to the small car with all the airbags? And the frontal crash? Looking forward to your answers!
