Obvoiusly I couldn't get a photo at that speed, but I got the license plate info at the next light. The white BMW 325is was heading NB on Kearney Villa Rd north of Miramar Way. Angry at the column of cars going 70 mph, he veered onto the shoulder/bike lane and accelerated to approx 90mph and cut the head car off. This gained him .5 seconds since I pretty much followed him to work (he works across the street).
