He doesn't want to admit he fucked up and failed because it would cast doubt on all his other half-baked ideas.
Tesla will definitely feel the pressure from other car manufacturers, but so far it has nothing much to worry about as the only really viable game changer as of now is the Hyundai Kona Electric. The new Audi e-tron was promising but ruined it with using electric mirrors which require your eyes to focus on far objects and near objects unlike a normal mirror, and heavy steel frame, which pretty much negates any excellent regen (due to heavy weight).
The Jaguar i-Pace is also a good alternative, but I feel like Hyundai's Kona E is an unbeatable value. Forget Chevy Bolt & Nissan Leaf....garbage.
The model 3 is seriously bad....did you see the interior? it's empty....its completely void apart from the giant tablet thing....the price is it's killing point.....now that there are are viable alternatives.
