Tesla sales were down Dec/Jan/Feb because all the factories producing the top selling Model Y shut down to re tool for the new Model.
Production is now ramping up to meet pent up demand. If FSD succeeds in Texas and is granted approval across the USA demand for Teslas will be through the roof.
Model Y is selling well.even in china and jiu hu. They have a smaller cheaper version of model Y coming out soon.
But overall, four mega factories in three biggest single market, maybe sales not as predicted.
