We were driving back from a hockey tournament with my dad, my coach, and his son. Driving on a highway in Ontario, we saw a super bright light in the distance that we were all trying to figure out. We thought at first it was a tower, or a plane with landing lights. It was VERY bright, but only white light. It was not strobing. After about 5 mins of driving it resolved into three lights, then four with a bright one in the middle as it passed the left side of our car, silently, at about 500ft (difficult to determine altitude without knowing its size). It was odd enough, looking like the photograph, that we were screaming and my dad pulled over, along with 5 or so cars who were also seeing it. The craft crossed the road behind us and accelerated off (not very high speed but faster than it passed us). I remember my friend and I being afraid it was circling around for us specifically and yelled at my dad to floor it, lol.
That was really all there was to the experience. All 4 of usn saw it, as did at least half a dozen other cars that found it odd enough to pull over as well.
