More chaos

Disasters aren't always caused by nature or by terrorists. Sometimes you just have some crazy bastard leaving his SUV on a rail crossing. Unfortunately, the allegedly suicidal man not only failed to kill himself but killed 10 people and injured 200.

See, this is why the Golden Gate Bridge people shouldn't be so upset that suicidal people use the bridge as a portal to the hereafter. Because jumping off the bridge is about as no-muss no-fuss as you can kill yourself. Most people who jump off the bridge don't even stop their cars in traffic -- they politely park in the parking lot, walk to mid-span, then leap. Compared to the Glendale train wreck, I'd say that's preferable.
