That said, it is pretty stupid that Space X has not been testing random parts
So uh... "Further testing of struts in stock found one that failed at 2,000 pounds of force"
Sounds to me like they likely were testing them at random and then decided to start testing a vastly significant number of them to troubleshoot.
A contractor is free to decide when and where the work is done. So Uber does not fit the contractor model.
And before anyone disagrees with this, I should note in duckintheface's favor that Uber penalizes drivers who decline too many fares, especially drivers of upscale services such as UberBlack who turn down too many UberX fares. Ergo, drivers cannot reasonably decide which work to take, reinforcing duckintheface's point.
A cab doesn't have this problem.
The more cordial the buyer's secretary, the greater the odds that the competition already has the order.
