The humans may be light... the car around them built to survive a 100mph crash certainly isn't.

  Sure but buses and cars themselves are strong enough and use rubber tyres. Not that I think rubber's a good idea for trains, but still.

    You really don't want to see what a 90mph crash in a bus looks like. It ain't pretty. Those speeds are unreasonable for a bus, but common on commuter rail in many civilized places.

  Imagine what airplanes would look like if we wanted to build them to survive a crash... I'm also a little unclear how humans could survive a 100mph crash even if their container makes it through. If they were wearing a 4-point harness, I guess? Do they build crumple zones into train cars? Or... just rely on utterly demolishing anything they hit so the deceleration is kept under control?
