"vehicle speed is not one of them (at least not directly). Yet the author and apparently others are intentionally driving slowly to boost their score? That doesn't make sense."

Makes LOT of sense, higher speed or driving at speed of rest of the traffic will require hard braking(>6m/h in 1sec) and turning.

Most insurance companies also seem to be offering these dongles which rate you based on your driving. What doesn't make sense is person can be "aggressive driver" without considering type and condition of their car. A performance car(BMW, Porsche etc.,) will be able to slow down or turn faster while being more safer than any CUV/SUV.

I don’t see how higher speed equates to hard braking and turning. I regularly drive 75mph on the I-5 in Washington (state) and never have to hard brake or turn. It’s just a matter of not following too closely—I aim for about 2s following distance myself, a number that was impressed upon me as a teen in Driver’s Ed.
