Yikes! VERY glad to read you are on the mend. What the driver of Car #2 did is why I am very distrustful of other drivers who wave me on (if on bike or in a car) until I can see the other lane, traffic, whatever has STOPPED (or there isn't any). In some places (I believe NJ, maybe not AB), the driver of Car #2 can be cited/held at fault for the accident.
Heal quickly, or at least completely.
