>Tesla did not release new cars, except for Cybertruck, for how long ? 5 years ? 10 years ?

As stated earlier, this is extremely bad strategy advice.

Tesla is battery-limited, not demand-limited (delivery wave concern trolling from OP's headline aside). Adding models would only add complexity without meaningfully increasing revenue.

It helps to know basic fundamental facts about the company before commenting.

  >Now there is a lot of competition and their lineup did not change at all.

More misinformation. Tesla continuously updates their cars unlike most manufacturers which are stuck in "waterfall" model year refreshes.

See Sandy Munro's excellent breakdowns on the phenomenal pace of innovation at Tesla compared to competitors.
