The idea itself wasn't that bad. This 2-section-principle is (in slightly changed form) still in use on many building vehicles. However, it isn't really good for long time road usage. First of all, you have loads of friction inside the hinge, which is also the car's biggest weak spot. I can also imagine that it's handling wasn't what you would call "stable" .
All in all, I can totally understand why it failed. Using two chassis parts connected over a hinge only creates more problems^^
