Give the guy a break, big deal he hit the limiter in first gear. The car is built for this sort of driving, though 6k is a better shift point in 1st. My zed is a tip auto and when I put my foot to the floor in auto mode it shifts up at 6k in 1st and 6.5k in 2nd and 3rd, the car is set up from the factory that way. If i am sitting at 60 on the motorway and put my foot down, the car will downshift to 3rd and head straight for the limiter.
It won't do it any harm if you occasionally hit it by accident after all that's why it's there, to prevent damage to the engine, just as long as you aren't driving about bouncing of the limiter all the time.
