In general, EV market share is a misleading metric since a decline for anyone holding a 100% market position is inevitable. Market share will drift downward as the number of deliveries from competitors grows; it doesn't seem rational to expect Tesla to retain 50+% of the US EV market share in the long term. Spinning that gradual decrease in EV market percentage as a dire concern reeks of an agenda.
It's also bizarre to focus on Model S, when Tesla's Q1 press release [3] says that Model S and X units are in transit overseas. S and X are manufactured in California and shipped to customers worldwide. Some of those customers have been waiting two years for their orders to be fulfilled. It's clear Tesla finally prioritized some overseas delivers of those two models to satisfy their shockingly-patient overseas customers. Contrary to the Jalopnik narrative, even with a large portion routed to other countries, US sales of S and X still exceeded popular media darlings (and good cars, mind you) such as the Rivian R1T (outsold by Model X) and F-150 Lightning (outsold by Model S).
