I don't think anything should change, or they should just get rid of it all together already. When the program was in full force, that's ALL you heard about from every news source, blog, vlog, youtube channel, and website (including my own). It was a horrible, competitive rat-race and I for one, am glad it's over. Now don't get me wrong, I ended up with a ton of referrals and all the event invites and prizes (swag, wheels, powerwalls, Roadster, etc) which I would not trade for anything, It was great while it lasted, but please, let's not go back there again! Even TMC was inundated with thousands of "use my referral code" posts of people begging for referrals. It was just ugly.
As originally designed, for friends to talk to and refer other friends and relatives (that is, REAL friends and family) to bring them into the Tesla universe, it was great. Or even talking up strangers who are asking questions. But I feel that that was a tiny, tiny, percentage of the referrals given out, and most referral points were given out for people who would have already bought a Tesla. Yes, it provided Tesla with millions of dollars of free marketing, but at what ugly expense? And I'm sure it was a nightmare to manage on the internal side without much forethought to what it would take to make all those awards and prizes actually work (like the Powerwall fiascoes and constantly changing policies I've posted quite a bit about). They're still trying to catch up with the Arachnid referral wheels. I still have one set owed to me I've been trying to collect for over a year now. Every time I ask the local Service Center, I get silence in return.
Also, I'd like to see more transparency from Tesla. Like the current program claims there's a MY referral winner every month, and a NG Roadster referral winner every quarter. It's been like that for what, a year now? Have we seen or heard from anyone who won those awards? And what about "Driving the Boring Machine" or "Race the Tesla Semi"? Crickets.
