They have had a market capitalization around $60B for over a year now. Something that Mercedes and BMW can't reach/maintain after being in business for a century+. There is nothing "suddenly" about Tesla's financial (market value) success.I don't know, if you are missing something, but you seem to have a short memory. It's great, that Tesla finally seems to have succeeded.
So which new/startup Western company has managed to reach greater success than Tesla in the last 50 years? Hint: there isn't any. No other company came close. The closest was DeLorean which imploded in spectacular fashion after producing less than 10,000 cars total. Something that Tesla now produces in about 8 days.I just don't think, they are a stellar example of, how you should run a company.
