Eh, couple things that throw that GIF off. The biggest to me - I highly doubt that cop would chase that biker at those speeds. When I was younger, I was being reckless like that and Cops would just hit their lights on and off to try to "warn" me to slow down. They wouldnt chase and they wouldnt "radio ahead." Ive heard something about it being more dangerous to pursue that behavior than to stop it? But I dont know if thats true. Never mind the pacing of the white lines, the mirrors, and the light refraction.
