I was just watching a PSA on Danish TV- a total mind-fark of a slow motion reverse horrific bicycle accident, where a driver who was adjusting his radio had hit a kid who was riding. The spot "undid" the accident through reverse, then warned about driving safely and not speeding.
I have seen all sorts of PSAs that deal with the themes of death (souls leaving the body for passengers not wearing seatbelts, but the one guy wearing his belt is 'trapped' by the belt and cannot leave/die). Additionally, the media often shows images of wrecked cars, including blood on the pavement--- and once I saw a bike frame under the wheel of the car (makes for nice breakfast reading).
I never saw those types of gruesome images while living in the US. Does anyone think these images promote safe driving? Or are they too gruesome? Are they merely tuned out? Also, why are bike related and safe driving related PSAs rarely shown in the US - except for DWI PSAs?
