Why doesn’t TSLA get included as part of mega caps, at 10x value of NFLX and almost twice the value of FB?

Not trying to start a flame war, but almost everytime I see mega caps mentioned, it's always the usual suspects, though much less mentions of NFLX of late.

For being around a Trillion in market cap, I find it strange TSLA rarely gets lumped into as mega cap, why?
