Did you ever know anyone who's diabetic? These things aren't an exact science - one might be taking their medication yet still occasionally develop problems based upon diet, exercise, etc.
The nice response: Then shouldn't we reconsider giving driver's licenses to people with diabetes?
The nasty response: I'm sure the person whose child is killed by some diabetic person having a hypoglycaemic crisis will be comforted by being told that it isn't an exact science.
I wonder if this shouldn't be considered. I don't know, I'm just wondering.
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.
