When driving on a well-lighted roadway? Mebbeso...

I have read that it was a well lighted road, but the video I saw did not appear to demonstrate that it was a well lighted road.

I drive down a well lighted road quite often, and I can see someone standing in the road from half a mile away.

The bicycle pusher was crossing just outside the limit of, apparently, the last streetlight. If I'd been driving, I might have thought to switch to high beams as I approached the dark area.

Maybe not; in a lighted area, at times, it's difficult to tell if your headlights are on --much less, whether they are high or low -- unless you go "eyeballs in" and check the instrument panel... (Like the "human driver" was -- until the last instant.)

Astronomers would say the cyclist was "just beyond the terminator"... '-)
