^^ Sad.
On another topic, I wonder how many people have medical conditions that could impair driving.
One of my sisters had brain surgery at the end of January and couldn't drive. Her restriction was pulled a few months after the surgery, but she still feels uncomfortable driving on a regular basis. She may feel great and drive to work, but by the end of the day the fatigue is too much and she can't drive home. Thankfully, she has a support system to pick her up and take her home, as well as the good sense to know she shouldn't drive.
How many folks don't have that sense and take the risk?
Your sister is awesome and a champ. I'm sure many wouldn't do that..and some probably genuinely would have a hard time not being able to drive.
