A machine with amazing lights that can swoop to ground level and go dangerously fast.they looked like three separate sets of car headlights racing on ground level, then they shot up at a 90 degree angle in an instant(about 30 feet off the ground), and formed a triangle, then shot back down instantly and took off, then did it again in a matter of a second or two. It was almost like it saw me the first time, took off, and then didd a double take. I could not believe how close these things were to the car. I then told the other two passengers in the front seat to look at what I saw. It sat in the same position shining it's three bright lights every 20-30 seconds from the moment I told the passengers until about 20-25 minutes later when the view of it was lost due to our elevation dropping on the freeway. We were on the I-5 freeway heading north, and everything I saw was on the East side of the freeway. I first saw it right where the I-5 and the 269 meet.Then, about 30-40 minutes later, we saw a similar light in the sky about 20 miles ahead and four miles east. Only, this light was shining two vertical lights whereas the other was shining three in triangular form. This thing would dive down(eg. "Superman the ride" at six flags) at unbelievable speed to ground level and zip all the way across the horizon within a matter of seconds and then go back up and stop on a dime in mid-air and do it's light thing again. It did this over and over again for about 20-25 minutes until we hit the 152 and went into th hills and lost sight of it. What we saw looked very dangerous and all three of us can't believe it didn't crash. If a human being was inside this thing then he/she deserves a medal for risking their lives. I'm a 25 yr. old male. The other two witnesses were a 29 yr. old male, and a 23 yr. old female.
