john submitted this idea :
I have my drive illuminated by a light pointing almost verticallty down -
the PIR senses the whole drive effectively without modifications.
The point of the site is to illustrate that pointing downwards is more
effective.

I agree fully with the effectiveness, I am just critical of some of the
designs of PIR light.

I agree - but mounting higher can help. On an estate I drive through people
use them as porch lights!
