I had 3 of my friends engaged into serious accidents (all males).
One got into an accidents because he...... sneezed.... twice while entering onto the roundabout. Other cars in front of him stopped, but he couldn't see that. Terrible, but funny at the same time post fact.
Other two guys got their cars canceled with an interval of 2 years because some speedy cars coming from the opposite direction and driven by drunk guys landed on the top of their cars. Terrible. I din't know what to say. Be careful? Doesn't work in this situation.
