2me. the DMV offers testing, if this becomes a concern.
I offer this counterweight.
A friend's children decided she shouldn't drive, so they disconnected the battery on her car and told her it couldn't be repaired. Of course, this trickery wouldn't work with your husband. None of these children had the time to take her to appointments or the store, so she'd ask me. She could make it to the grocery store, but couldn't carry the groceries back. She was skipping her doctor's appointment because it was two busses across town. And she hadn't seen her best friend in months. I wasn't in on the plot, so was easily able to have her car "repaired," but by then her license had expired. I took her to the DMV where she aced all the testing. The employee who tested her took his break to give me the most wonderful lecture. Thinking I was his daughter, he let me know in stern terms that driving is a privileged that I had no right to deprive her of.
Stay on his side; let the DMV decide.
