| are lazy and don't care about others - for example high beams
| should be disabled _before_ other car ahead is already visible
| on winding road , same goes for hills and multitude of other
| various scenarios where automatic sensors and software just
| doesn 't work. Tbh it seems that this is another "arms race"
| just like with car size/SUVs dominance and this arms race can
| make driving at night really painful experience

| Edit: I just googled it. That's exactly what's happening - EU
| side mirrors are curved to prevent blind spots.
