Does SpaceX recover the second stage?
As of 2017 SpaceX had spent over a billion dollars on the development program. By late 2014, SpaceX suspended or abandoned the plan to recover and reuse the Falcon 9 second stage; the additional mass of the required heat shield, landing gear, and low-powered landing engines would incur too great a performance penalty.

Is 0 to 60 in 12 seconds fast?
Not fast, but faster than at least 50% (probably closer to 70%) of all of the cars on the road. If you are taking about common mid-tier muscle cars, that number would drop to around 4.5 seconds from 0–60 MPH. This would be a more above-average number.

Why does SpaceX recover second stage?
So the propellant was vented into space, and the second stage was set to make a more uncontrolled re-entry into the atmosphere. In this case, the Falcon 9 upper stage still comes back because when it released the Starlink satellites, the vehicle was orbiting Earth at an average altitude of about 250 km.

Typically, a Falcon 9 rocket makes a more controlled return to Earth. Its second stage returned to Earth three weeks later.
How fast does SpaceX travel?
The SpaceX Falcon 1 rocket, Falcon 9 family of rockets, and Falcon Heavy all attempt to reach orbital velocity. Low orbit around Earth requires a velocity of 17,500mph (25,000kph, 7,800m/s). The second stage of the SpaceX rockets thus reaches a minimum speed of about 17,500mph (25,000kph, 7,800m/s).
