Looking at the trains, they have no bumper and are sure to chew up anything in their path. Couldn't we design and build some kind of tough, inflatable bumper and install for a reasonable price? Yes, you would get badly banged up (watch the 3rd rail!) but would probably stand a better chance. I'd also like to verify the average actual cause of death before fully backing this idea.
