In most cases yes you cannot over rev by driving it forward, but downshifting is another way of over revving the engine (for example your 5th to 2nd). Downshifting while the car is going 80mph in 5th to 2nd makes the tranny and engine shootup to like 11,000rpms. Rev limiter cannot stop a stupid driver.
