Seriously. If you hit the rev limiter on any engine you shouldn't be driving.
The rev limiter is not there for your convenience, it's there to keep the engine from blowing up due to whatever stupid thing the driver did (down shift to too low of a gear at too fast a speed, not upshift fast enough, floor the gas in neutral, you know, stuff people who know how to drive a performance car properly would not do).
This is not the old days when engine technology was so primitive that the "rev limiter" was the maximum air and fuel your carburator could feed the intake manifold. Today, if it were not for computer cotrolled limiters, a fool could hold the gas down or shift wrong and BOOM! Good bye engine.

If the rev limiter was set up the same way as the Porsche you describe, I'd agree with you but GM erred on the side of caution. Also, your point about "shouldn't be driving" if you hit it does not take into acount those who power shift a car when racing which is what I do. RPM's drop in between gears for most cautios racers. RPM's rise in between gears for power shifter. This must be done so that the RPMm falls into optimum speed for the next gear.
