Perhaps utilizing an old, highly effective, proven system should be considered for your needs.
This particular system is the choice for all truckers and large equipment movers.
Its simple, easily understood, quickly learned. Yes, I'm recommending you & wife start using hand signals.
Altern,
We aren't new kids on the block. Used hand signals for years. But if you've ever been in a tight spot you will know that sometimes it is much better for the spotter to be in a position not visible to the driver. A hand signal does little good then (except maybe as an indication of opinion!)
I do appreciate those of you who have responded seriously and will consider all suggestions carefully. Thanks.
