I think it's a minor stroke. It can relapse easily and there's sufficient time to response, eg slow down and stop the vehicle and go to hospital within an hour.
Having said that,
- Do i interpret correctly that there is no "case" (punishment), so she resorted to voice her grievance in social media?
- The hubby should do more, if he is able to drive now after recovery from stroke, the articles appear to hint that he is hiding behind the curtains.
