In the USA the market share of light trucks was 73% in Q3 2019. Those are 100% not Tesla's.
Tesla's revenue is ~23% of BMW group's revenue. Impressive for sure but they are not destroying anyone.
It is also estimated that if Ford and VW bring an EV on the market they will easily sell 100k units with their first model.
The world market is bigger and different than you think. The German brands are loved in China. And markets like Brazil are upcoming.
