That is actually less of an issue as you might think, if the light is designed properly. As you will have to look at the corner before you ever shine the light directly towards it. This is not much different from motorcycles.

Since this is a vanmoof (first edition probably) I think they followed the design of "old fashioned" bikes which also lack the turnability features as the light is attached to the frame part of the central steering bar and not the insert which turns with the steering wheel.

I consider that an advantage because the light stays nice and steady while I weave around bumps in the road.
