Horrible! My husband was hit in the same way, but escaped with only terrible bruising. He was also hit early afternoon on a Sunday. I don’t know how much a blinkie or bright(-er he was wearing bright red) clothes would help in the middle of the afternoon. Maybe at dusk or early morning. Other than towing a 8 foot neon sign that says “DON’T HIT ME” there’s only so much we can do to make ourselves visible, then at some point the responsibility falls to the car driver to PAY ATTENTION. No amount of neon makes up for a cell phone, kids in the backseat, changing the radio, etc.
