Whilst true....with a sequential shifter, you then need to remember not to go for an H movement....ie dot hit a downshift when you were aiming for another upshift. So risks still apply.

There are pros and cons either way. It should be impossible to mis-shift a sequential, but it can be done. And in some respects there stands more chance of damaging forks etc as you might try and ram gears faster with such a shifter as there would be slightly less feel under hand as to whether it wants, or doesnt want to go into gear.

And manufacturers would never offer a mechanical setup like this, as it would be a ballix in normal daily driving, forcing you to go through every gear to get to one end or the other.
It's often nice with an H just to drop it into neutral approaching lights in traffic etc, or just miss the occasional gear when going up or down.
