I keep a keen eye on worktrucks & job sites when I’m riding. That’s mainly because of the woman who got decapitated. Sad story. She was just minding her business, walking to work, or the shops or wherever, when she strolled by a construction site & bzzzzsssswhoosh! A saw blade came flying from where they were cutting a pipe and she was gone. Her body on the pavement, her head in the road. Ever since then I’ve made sure to maintain a healthy distrust of men in hardhats operating heavy machinery.
