Wouldn’t use the word supremacy, pioneer might be a better term primarily as teslas are now getting major technical competition from the newer ev makers like lucid and rivian while legacy automakers with better production quality and history of reliability are catching up to them in battery, bms and software integration also Tesla themselves have their own issues which similar to Ather are rarely discussed beyond it’s community forums. Charging network and standards is the only place Tesla has hold up its lead in US but the charger standard game won’t work for them across the pond in the Eurasian markets.
