No. They follow curves and have blank spots when shining at an oncoming car.
That’s why i leave them on until i see someone. But it’s nasty to have lights in your eyes.
Better lights in the eyes than Tesla tire treads, at least…
Not owning a Kia I can’t answer for that but in my Bolt the optimum speed for max distance is 45mph. Above that it slowly declines as speed increases to 65 then it drops off a cliff. Accordingly when I’m on the road I stay in the right-hand lane at 65mph, the same speed as a lot – but not all – semitrailer trucks.
