Interesting take on flashing lights for trucks to pull in after they pass you. As a Brit expat who did that all the time in the UK, I found that flashing lights here in NC had absolutely no effect on the driver of the truck. Back in the UK, a flash after they passed was met by their indicator flashing to show they were changing lanes, and then a flash of hazard warning lights as a “Thank You”.
Kimberley is obviously expecting drivers to actually know what all the extra stuff in their cars is, over and above the “go” pedal. LOL
