A friend of mine was on the light rail here downtown when it stopped unexpectedly. He was confused and walked outside only to see the train had hit a fire truck and pushed it nearly a block before it stopped. He had no idea there was even a collision inside the train. Trains are very scary stuff even when moving at a crawl. A 110,000 ton ship collision is something the human brain is just not going to understand intuitively.
