Tesla achieved something tremendous. NASA had failures on the way to achieving something incredible, such as landing on the moon. Space X did have failures on the way to being able to land rockets to the same place they launched. You can't only dwell on failures on the way, and dismiss the tremendous successes.
It's ok to stick to admitting you are wrong to say BB went bankrupt, rather than trying to continue to trash BB and Tesla.
Tesla shares are volatile. Stock prices aside, you say Tesla "have 2 models that they can’t even figure out how to produce". Tesla did produce many model S and X, and have many satisfied owners. Instead of explaining your statement, you trash those owners as "one or two wierdos".
Instead of only insulting Tesla owners, or make statement that you now admit is wrong, how about coming back with facts. It'll help if you also learn how to spell.
