Litter pickle

 I sometimes see a road sign "picking up your litter risks roadworkers lives". And I wonder, if that's the case, and yes, it must be the case, how can the employer possibly justify the activity when they're doing their risk assessment paperwork. Obviously it needs doing, but.. 

I figure this is what the robot "dogs" in that Black Mirror episode, "Metalhead", were originally invented for.  They started off picking up the litter as replacements for human roadworkers, and then their AI twigged it would be more efficient to get rid of the cause of the litter. 

Stab stab stab, kill kill kill. 

At least we're biodegradable.
