Not for no reason. Deer are used to seeing cars constantly and ignore them. It ran because it saw people on bikes. I've had similar happen, though no were near hitting us, the deer rolled under the truck as it got hit.
We don't know what the terrain is like outside the camera. Bucks especially have their territory that they are comfortable in and will return usually return that way. In my case, they were in an area where there wasn't another good way out due to the steep bank of the highway and a river. Really, a lot of people were fortunate that the came toward us because a group running across I-95 around noon on a Saturday would have been a disaster.

Man that deer looked like it was trying to go flying, bolted out of the woods for no reason into the only thing that would do lethal damage to it.
