/r/Rivian is a class act. I expected a wall of screaming, but instead entered a relatively calm room. People are upset, but there's no seething or flamewars, which is kind-of surprising given the cost of these trucks ($80k+, Range Rover territory).
I think the reason is because they're $80k trucks, not $400/month Tesla leases. Also, they're first generation and I think most of the buyers understand that.
