I was on Highway 205 in Tracy Ca. On May 3 2014. Earlier in the day I saw a triangle on 680 in Sunol but was unable to get a picture. On my way home at 330 that morning as I was traveling on 205 in Tracy I saw a bright light coming from my left side just as I passed MacArthur. I thought it was a helicopter because it was traveling so low. As it got closer I could see the triangle shape but it was not the same as the one earlier. The one earlier was a boxed shape and shaped like a boomerang. This one was a flat full triangle. I took a couple of pictures as it came towards me and one as it went over the top of my car with the sunroof open. It headed over the Altamont and disappeared in a couple of seconds. The picture of it coming towards me has to be spread open to see the shape. You won't see the whole craft only the lights in the triangle form and the picture of it going over the car you can't see a shape only a weird light form. The last picture is of it flying over a large distribution warehouse on the right side of the car after it passed over. I see them all the time, I don't know why. I've even had one stop 50 yards in front of me totally invisible. I felt is presence in front of me, I couldn't see it I just knew it was there some how. It sat there for a couple of seconds as did I because I was so in awe I couldn't move. It took off leaving a blue steak behind it that looked like a huge blow torch.
