No draws have been announced, the referral scheme abuses supporters nowadays if you ask me. If you'd got solar I think the referall is worth a cash amo8nt and it always seemed more sensible to me to giver people say $100 for making a referral rather than free supercharging which nobody can accurately work out how much they actually get as miles doesn't equate to how they give it out.
As for the roadster, I think they need to come up with a drive train and battery design first that meets the promises. I strongly suspect they'll do the plaid MS as part of a revamp and that will be the basis for the roadster.
