Lol where do u get your source from? Seems u and others hear what someone saids and just regurgitates the same thing...
Research your cars a bit more, in the past, yes, but not current, as far as Japanese cars go LFA, Supra, 300zx, GTR, FRS, etc.... One example : Japanese were perfecting electric steering on the NSX and that car was waaaay ahead of its time before the Germans even did electric steering and yet still can't get it right
Historically, the Japanese when it comes to tech in their luxury cars waited for the Germans to come out with the tech, as the Germans used the customer as guinea pigs...when they worked the clichés out, the Japanese would perfect that tech. They also took to bringing things to market a long time. Lexus is well known for this. And this one of the reasons why lexus and other Japanese manufacturers have a rep for reliability. The LFA went thru several iterations, and had to be re-engineered, brocade it came out.
The FRS is the result of Toyota's top man wanting Toyota to have "drivers" cars, to have fun. The GT-R would be still a Concept if it wasn't for Renault's money and Ghosn at the helm.
300zx, was good (I want one), but a result of the 90s pricing.
The new 911's with their EPS are damn good.
NSX was great, but long in tooth...still looks like an exotic today, and was one of the reasons. Why Ferrari brought out the F355.
Bottom line, it's a cultural thing with Japan and the corporate/car/product culture. It's like a tool , a tool must be reliable. An appliance must be reliable, so it's designed that way. Not to say that new tech cannot be put into the design, but untried new tech, defeats the purpose of reliability.
The Germans want to come out with all types of new tech, just look at the "new" S class (on the same chassis as the "old" S class, just like the "new" Lexus LS), all this new tech that they brought out.
