Here's the spot where I believe he got on A148 based on the description (heading east out of Holt, turned right around the bend where the road joins A148) https://www.google.com/maps/search/holt/@52.9119877,1.114502...

I used streetview to follow along the road, it is a 2-lane that has sporadic houses and somewhat wooded, there is a sidewalk on the left side or the road. Speed limit signs say 30 km/h (so just under 20 Mph). After the residential area (1.3 km), it opens up to mostly farm field for another 1.5 km, then it hits another residential spot. So the description of "just winding through the gears" would put it probably at the end of the first group of houses, where it makes sense that residents would be walking (there is a payphone and a bus shelter in the middle of that stretch of road).

It says the victim, Rawson, had just exited a bus, and the driver was ramping up in gears - shortly after the left turn off the A148, as a bend begins to straighten out, there is a hidden bus stop on the left side of the road: https://www.google.com/maps/@52.9118915,1.1132237,3a,75y,231...

There doesn't appear to be any obvious lighting in the area; it may be the oncoming driver flashed because they could see Rawson was in the road and realised the oncoming driver wouldn't have seen him, having just come around the bend.

UK speed limits are in Mph, not km/h, so it is a 30 Mph road.
