Oh, true!
The if_speed variable is in the wrong scope.
I'd say fixing this is a separate patch though.

But somehow the interface got there, so maybe it has its purpose?
I also think this change of treatment of error is the topic
of another patch that broadly changes the error treatment in this
function, as you suggested.

Could we get this CID fix in now and do further improvements
(directly) afterwards? I'd be willing to argue to do the
speed = 0 in this special case.

Thanks - Michael
