I love how people are considering RR crossings an "edge case". It's been something FSD / Autopilot haven't been able to do and it seems like one of those, absolutely should be able to before being allowed in production kinda things.
Elon is designing for the future when all railroads are replaced by superior hyperloop technology. Why bother designing for a legacy feature? Next you'll suggest that the vehicle should avoid running over pedestrians and cyclists.
multiple people have already died with strong links to their use of AI products; I mention this only to say, if it hasn't happened already, a car wreck doesn't seem likely to be the deciding factor.
Who, out of curiosity? If it's anyone at Tesla or Waymo, I'm curious what they have to say. If not, it's more armchair stupidity.
