Good idea, considering the diminishing numbers of drivers who know how to drive manual transmission properly.
I once had a roommate who bought a RSX-Type S but couldn't drive stick, so I had to drive it home for him. He then proceeded to teach himself how to drive stick... painfully... oh the horror...
Good point about dropped clutch at high revs and associated damage, not sure the 4K limit for neutral will do anything to prevent that. That kind of abusive driving using is done with car in gear (and clutch in).
