Back in world war 2, the carburetor powered planes could not hang with the fuel injected planes on dives and climbs. Once the fuel injected planes started doing climb and dive maneuvers in a dog fight, the carburetor planes would stall out.

The link you provided makes it clear that the fuel injection system was used to help the plane operate during extreme maneuvers, which cars do not have to go through. There's nothing there that shows any advantage for cars.
There's a few problems with this article:
1. It's a lousy article, no real explanation of anything or any indication of who wrote it.
2. Its comparing carbs to fuel injection as we know it now, with the computer controlled systems that make it work. Computer controlled fuel injection works very well and have many advantages, the earlier mechanical fuel injection that was competing against carbs back around WWII did not. The idea of fuel injection was decent but the rest of the technology to actually make it work well would take decades to arrive. It only became possible after the electronic systems to control it were created.
