I am so sorry for your loss. My son, age 20, was on a bike in a bike lane near his university when an elderly driver turned right in front of him. She even saw him at the top of the hill and just about 10 seconds later turned across the bike lane. He died from his injuries. I am forming a non-profit organization to educate everyone about changes that affect driving as we age and advocate for screening older drivers before they can renew their driver's licenses in all 50 states. I am so sorry for you and your family. My family is also forever saddened and changed.
