Sorry in advance for nerding out, but unless you're referring to Ferdinand (the older one who worked with the Nazis, not his son Ferdinand "Ferry" Porsche who build the first 356) Porsche's time at Daimler and Auto Union, you're wrong about Ferrari. Enzo Ferrari was a race driver for Alfa Romeo and lead his own racing team by the early 1930s. Ok, there weren't any Ferrari-
cars around, they still tuned Alfa Romeos back then, but the Scuderia Ferrrari won the Mille Miglia in 1940 for example.
Building race cars was basically everything Enzo Ferrari wanted, he hated to build road cars for customers and only did so to get the funding for the racing division (read up on how the "selling Ferrari to Ford" didn't happen, it's a nice story and shows how Ferrari was all about racing back then).
By the time Porsche had build their first competitive race car with the 550 Spyder - a car that was still using a swing axle suspension and a 110hp engine based on the beetle engine which was more or less stolen from a Czech engineer in the Nazi era - Ferrari was already about to win Formula 1 for the 3rd time (out of only 4 F1 seasons; F1 only exists since 1950). And that was only Formula 1, Ferraris were winning in just about every racing discipline around, for example Ferrari cars had won the 24h of Le Mans
seven times when Porsche was around for their first Le Mans victory in 1970.
I'm a Porsche fan myself, but we shouldn't dismiss Ferrari for the "franchise"-mistakes primarily made in the 2 or 3 decades after the 80s. Your description fits Lamborghini much better in my opinion and I can absolutely see why Ferrari and Lamborghini would be seen like that, but that is selling Ferrari's racing history short.

It's just on my wishlist and I haven't played it myself yet, but I was definitely more sold on the content of BeamNG after watching it played on the GiantBomb Extra Life stream this year. Drew is a bad driver, but having Danny and Alexis on the couch laughing about the mistakes and crashes is really brilliant:
