most cars dont shift to 1st unless they're basically stopped.
including, in my experience, r33, lancer, rav 4, ss ute, fpv. the clapped out barina did. lol. but thats another story.
considering i can take off in 2nd with no probs in my 33, why would you wanna shift down to 1st at 20kph anyway?
edit: speeling speling, spelling ><
