The insight could help physicists reconcile quantum mechanics and Einstein's general theory of relativity

What? QM is COMPLETELY in line with relativity. If you had FTL communication, it wouldn't, but that doesn't exist- quantum teleportation requires a classical channel to relay information (namely, which state Bob's particle collapsed into). I admit I haven't read the linked articles yet, but I doubt the authors made any such claim (and that was input by the submitter/editor)

The research into quantum computing is using done with the goal of a universal quantum Turing machine, which would, by proof, run classical algorithms in addition to quantum ones.

Not the D-Wave. There's two branches in current quantum computation: General quantum computation, which is still stuck at the implementation stage (of which languages like QCL derive) and D-Wave's computation (which, admittedly, is geared toward quantum annealing and no other quantum procedures, and is therefore not a general quantum computer).

If I were to think a few years down the road, the path D-Wave is taking would culminate in chips that do specific things, such as perform quantum communication protocols, but only those things that were hardwired into the chip. It's hard to think of how a quantum operating system or a quantum programming language would operate under such a model. The general quantum computing path, for which four major quantum programming languages have been written already (QCL, LANQ, CQPL, and QML), if possible, would allow for Turing-Complete machines.

Bad driving isn't simply "speeding over 70mph" (aren't some highways over that speed limit anyway?), it's an amalgamation of not paying attention, not planning ahead, and not conforming to how everyone else is driving (to an extent). The problem you pose isn't solved in any way by this technology, and it gives more "bad driver" false positives than correct predictions.
