He Blew His Mind Out in a "Car"

The Beatles' song, A Day In The Life claimed to be about Tara Browne, the Guinness heir who died in an automobile accident in 1966.  The car he was driving was a Lotus.  In 1968, the Beatles recorded a song Glass Onion that has gained notoriety as a "Paul is Dead" song.  It's very possible that (what I believe was replacement) John was talking in both songs about the Lotus bed, a single-man hyperbaric oxygen chamber.  Photo is above.  Discussion will follow.
