Silver, how sad. I'm sorry. I'm glad the guy wasn't alone when it happened, though. There have been several fatalities in my city recently, and some non-fatal hits. A woman from our cycling club has been in the hospital where I work for weeks- broken back, broken ribs, broken femur- but got to go to rehab last week finally. It was like a daily reminder, seeing her name in the computer every day. She's lucky.
I know what you mean about injuries not appearing that bad. Maybe someone from the cycling club will have more information. One thing that easily kills people is when the aorta is injured during a sudden deceleration.
I copied this from the bicycle safe website. It's not much, but it's something.
The Left Cross
A car coming towards you makes a left turn right in front of you, or right into you.
How to avoid this collision:
1. Don't ride on the sidewalk. When you come off the sidewalk to cross the street, you're invisible to turning motorists.
2. Get a headlight. If you're riding at night, you should absolutely use a front headlight. It's required by law in most countries, anyway.
3. Wear something bright, even during the day. It may seem silly, but bikes are small and easy to see through even during the day. Yellow or orange reflective vests really make a big difference. Reflective leg bands are also easy and inexpensive.
4. Don't pass on the right. Don't overtake slow-moving vehicles on the right. Doing so makes you invisible to left-turning motorists at intersections. Passing on the right means that the vehicle you're passing could also make a right turn right into you, too.
5. Slow down. If you can't make eye contact with the driver (especially at night), slow down so much that you're able to completely stop if you have to. Sure, it's inconvenient, but it beats getting hit.
