According to the latest data from the European Automobile Manufacturers Association (ACEA), sales of Electrically Chargeable Vehicles (which include plug-in hybrids) in Q1 of 2017 were brisk across much of Europe: they rose by 80% Y/Y in eco-friendly Sweden, 78% in Germany, just over 40% in Belgium and grew by roughly 30% across the European Union... but not in Denmark: here sales cratered by over 60% for one simple reason: the government phased out taxpayer subsidies.
I think it's safe to say there would be similar results in in the USA if states and federal government didn't subsidize Tesla and it's vehicles. There's cheapest vehicle would probably cost more than 100k if the government treated them the same way they treated other auto manufactures.
Tesla, Amazon, Google and Facebook all look like dot-com companies from the 90's with plenty of growth but no revenue to show for it. These companies are being heavily speculated in the markets because other markets like energy, mining, manufacturing and finance are all doing shitty. So these tech companies are the only bright spot in the markets which most of that is because government taxes and regulations are still very mild for tech and the internet industries.
Can you say bubble? This is exactly why you shouldn't invest in Tesla. Almost a million dollars per car sold is unsustainable. Someones going to make a ton of money shorting these stock when the market collapses.
