I wonder if some might consider:
a) switching to a 6-50 which has the ability to charge at the same rate and will most likely become the default 240v adapter in due time since their is no EV in North America that requires a neutral for 240v charging. The 14-50 is a carryover from the days when us 2013 and earlierer's required a campground 14-50 for road tripping before the amazing supercharger network locations became plentiful
b) purchasing a Tesla 14-30 MC adapter, remove the neutral prong (which is a dummy/dead/extraneous prong) and charge on one’s 14-50 that will automatically self limit to pull 24A with no manual intervention for a ~22mph charge rate
c) going with a 240v 30a circuit, NEMA 14-30 receptacle, and matching Tesla adapter
d) going with a 240v 20a circuit, NEMA 6-20 receptacle, and matching Tesla adapter for a ~15mph charge rate
