Driving IS! Especially when I may be coming in the opposite direction!
I assure you, my family will not be comforted by the fact that I was killed by a diabetic who "was having a problem with her dosages because of diet and exercise".
Let her figure it out, and when she's problem free for about a month, then she can drive.
It could just as easily be someone who had a heart attack, or slid on ice, hydroplaned on water, etc. If you and your family are not willing to assume those risks, then don't get on the road.

A diabetic friend of mine would sometimes go months between episodes. So your standard wouldn't necessarily prevent anything. Like I said, these things aren't an exact science. If you know anyone who was diabetic, you wouldn't be assuming it is.
