Very sad situation.  Please don't forget that, regardless of the situation, simple physics will determine the "winner" in car/bicycle collisions.   

From the Insurance Institute for Highway Safety:  " In a collision involving two vehicles that differ in size and weight, the people in the smaller, lighter vehicle will be at a disadvantage. The bigger, heavier vehicle will push the smaller, lighter one backward during the impact. This means there will be less force on the occupants of the heavier vehicle and more on the people in the lighter vehicle. Greater force means greater risk, so the likelihood of injury goes up in the smaller, lighter vehicles."
