We are all familiar with the term 'Range Anxiety'. Tesla has solved this with the superchargers, but has created a related anxiety: 'Supercharger Anxiety'. This anxiety appears to arise from three concerns: 1) Will all the supercharger stalls be occupied when I arrive, either by other cars charging or ICEd; 2) Will only a single spot be open and therefore I will have to split the charge and thus prolong my stopover and 3) Will the supercharger be functional. I have experienced all three. Last summer, multiple stalls at the Tejon Ranch supercharger were down when I arrived (another thread today indicates this has happened again). This week, I drove to Vegas from Southern California via the Barstow supercharger. I experienced anxiety about all spots being occupied and/or only a single spot being open. Both turned out to be true on the outbound and inbound trips. While this does not bother me, it is a major problem for my wife and kids. This is the crowd Tesla needs to make happy to get widespread adoption of BEV.
I think Tesla is working to fix 'Supercharge Anxiety' with more supercharges and more stalls per site (this approach has appeared to work at Gilroy). However, I would have preferred that they had first focused on improving the high-use supercharges like Barstow before making a cross-country route that very few will use.
