From what I gather (correct me if I'm wrong) this is mainly for people with uprated clutches. Me being one.
I'm sure it's still a 'concern' with a standard clutch, so I'd imagine if you can get into the habit of starting off the clutch in neutral, then no harm done.
It's almost ingrained into me though, depressing the clutch.
And to those who are slagging this guy off, for solving a problem and building a little business around it, maybe just don't comment at all?
