With Musk leading this amazing effort to advance human space exploration, maybe I'll start thinking about buying one of his Teslas.

In a couple of years we might hope Russia will lose most of its Global space cargo and passenger business to Spacex.  In fact, to reach an economy of scale where reusable first stage rockets are cheaper than disposable stages, Spacex has to launch an awful lot of them and that has got a lot of higher cost, Sat.  launch companies, worried.  The reason is that reusable stages must carry 40% more fuel to return, reducing payload accordingly, increasing the number of reuses to break even.

Even with expendable rockets, Spacex's Falcon Heavy will greatly outperform Airbus/Safran's Ariane 6...twice the payload to geosynchronous transit orbit at $10,000,000 less cost:

Falcon Heavy's planned first launch is at the end of 2016; Ariane 6 is not planned to be operational until 2020. According to Spacex, the Falcon Heavy's payload capability for Mars missions will be 13,500 kg.

As advanced as Spacex is in the space launch industry, Musk's Tesla is in the automotive world. The Tesla 3, only $35,000 and due for 2017 delivery:

Might be time to upgrade my ride in the US from my classic 26 year old BMW 535i (with manual gearshift-rare!) to a Tesla 3 (with the $ I save by not owning a car in UA).
