I was coming back from dropping someone off at LAX this morning when I spotted a mineral grey 05 GT. Traffic was pretty heavy as usual and I was near him for awhile until I got around some people and was able to get into some clear. I was able to set the crusie control at 75 mph and I couls still see the GT in my review changing lanes. I was one lane over from the fast lane and I saw him pull behind an SUV in the fast lane I would say a good 1/8 of a mile back. The SUV moved over leaving no cars at all in the fast lane and the GT gunned it and started gaining on me VERY fast. I still had my crusie control on at 75 mph but he caught up to me within about 5 seconds and FLEW past me at what had to be at least 100 mph
