Bikes and cars, not a good mix. All of these are people I actually know, but obviously it's anecdotal evidence.
Older avid biker tangled with a car and has a severe spinal cord injury somewhere in the neck area. Slowly regaining use of extremities after a year.
Another near retirement age, also cycled regularly, crashed into a suddenly stopped car, concussion, never been right since, memory loss and slurred speech.
One of my closest friends, top junior cyclist in the US, front wheel collapsed (no car involved), flipped over the handlebars at high speed and broke his collar bone, it set about an inch different from the other side. He dies in a car crash several years later, just him, the car and a telephone pole on a turn, he never turned or touched the brakes from what they could tell.
So, yeah, my totally unscientific experience is that bikes can be bad, around cars deadly.
