2 bmws racing their cars at 7pm down sand canyon. All other cars were driving safely around 45 mph these cars were going 80mph , I almost passed out when the car approached right behind me at deadly speed then immediately weaved in front of another car on my left lane. I notice eventually they went into woodbury town center. Dark navy bmws x5. they will kill someone someday. I almost passed out , I have 2 four year old kids in my mini van.
