On Foxnews they just had a heli following a BMW in a police pursuit
(Texas?). About a minute after I turned it on, they said the police (cars)
chose not to continue the chase. The heli still continued to monitor the
BMW as it seemed to slow down, at least compared to the other drivers
around on the interstate.

Well the BMW's driver just got in the leftmost lane. A black F150 came up
from behind almost out of nowhere. It appeared he was one or two car
lengths behind the LLB BMW for about 5-10 seconds before having to pass on
the right.
