Tesla Model 3: Company releases its most affordable car yet but few people can actually buy it

Tesla's newest car is its cheapest ever, by a long way. But that doesn't mean you can actually buy it. The company has released its Model 3, the long-promised affordable version of its innovative electric vehicle. It costs half as much as the cars Tesla has made before – but won't arrive until at least 2018. There are about 500,000 people already on the waiting list, who've given Elon Musk's company a deposit to reserve their car.
