Everyone could exercise a little more caution (in life, not just when driving). Just be happy you're still alive. I was involved in an accident with a pickup truck a few months back where I was hit from behind as I was crossing over to the left lane. It was my first and only bike-related accident where fate wasn't in my hands, but now my hair raises a bit every time a car approaches from behind. I think long and hard before going on long-ish solo rides now.
