Since Tesla is selling in Europe don’t they already do this over there? So should be easy if so. Also we have been rear ended in related to fog and it’s no fun and a long recovery! Until we develop shields maybe we can help prevent this in fog and just other people not paying attention by adding both the fog light option and a flashing top brake light bar when initial brake touch or releasing off the accelerator pedal this would all help keep our cars out of the body shop and bodies from injury. (Disregard last part if already flashes, still working on acquiring my MS)
