. Once you've seen them, you can of course pull that stalk... 
Precisely. You should be monitoring the situation and in some situations may need to pull the stalk. All driver aids currently need to be supervised, with the driver in ultimate control. But some drivers are lazy and leave it to the car ,or may never have been taught there is a need, or the hazard perception skills required.
How many who have only ever driven a car with auto lights will have the empathy to realise they might still be dazzling pedestrians etc .
Old git rant - Some will have little experience of being a pedestrian. Always Dropped off at school by car .Many young adults near me will wait 20 minutes for a bus and pay £2 fare rather than walk downhill for 15 minutes.
I always walk there and back, even though I have a pensioners bus pass. How they can the youngsters ever afford to commence a lifetime of buying vapes?
