I cycled home after a night shift and remember none of the ride. Was I conscious on the way?

Twelve hours on, then six kilometres home along the river in the half-dark. This morning I got off my bike outside my building and realised I had no memory at all of the ride. Not the lights at the bridge, not the roundabout by the station. Yet I must have stopped at red, signalled and steered round people, because here I am.
A colleague sent me the example philosophers use for this: David Armstrong's long-distance lorry driver, who "comes to" after miles of road he has driven perfectly well and cannot recall. Armstrong's verdict, as I understand it, was that the driver was perceiving the whole time but was not aware of his own perceiving. There was seeing, but nobody noticing the seeing.
That leaves me with three possibilities:
- I was conscious of the road and simply laid down no memories of it.
- Something in me registered the road, but there was nothing it was like to be me on the way.
- The question has no answer, because "conscious" covers several things that usually come together, and this morning they came apart.
Which is it? And is there any way, even in principle, to find out, when the only witness is the person who forgot?
