im surprised too - I have a lot of friends that are fascinated by my tesla and have come along for rides etc but I haven't been able to convince anyone to go electric - they all buy or lease a lexus, BMW or Audi
I've not gotten to use a referral code once even in 4 yrs of ownership.
I think if there's more incentives, for example if our work had EV preferred parking or better yet free or cheap charging that might be an incentive? They ought to give HOV access for life for all ZEV electric cars (not the PHEV/hybrids) and maybe even phase out carpooling and incentivize EV and make it an "EV" lane.
