When we got our Model 3, late last December, the first few times around the holidays we encountered lines for Superchargers in SoCal. Since then, we've taken a few longer trips and never had to wait -- including one on MLK long weekend. During regular weekends etc. it is never a problem -- also, if it WAS a problem, there's always an Electrify America charger nearby, so there's that if you want to get a chademo adapter. I'm probably getting a Y next May but I am interested in the Mach E. What gives me pause is the lack of supercharger network and I am skeptical of the range numbers published by Ford. I'll probably get a Y and have 2 Teslas.
