glad you didn't hit them. it can be pretty crazy. i've never hit a deer myself, though my brother hit one on his motorcycle. knocked him off and put him and his bike into a bunch of mud just off the side of the road. totalled the 2-month-old SV-650 because after the hit, the bike went straight into a curb, taco'd the front rim, bent the forks and cracked the head tube... along with all the other damage from when it finally landed.
meanwhile the deer kept on running after it got back up.
Same thing happened to my brother in Oklahoma.
He was driving back from work at night and saw deer running across the road.
Not small ones, those were full adults.
He slowed down enough to let them all pass or so he thought.
As soon as all was clear and he sped up, another big one came hopping from the other side to join the group.
No major damage inside but car's hood was pretty banged up and so did the deer.
It laid on the side of the road unconscious.
He called cops but they said they can't come so the cops called a local farmer in that area who came and shot the deer and took it for some good eating.
I have encountered many but never hit one thankfully.
Antelopes and elks are even worse.
They are big and very uncooperative.
I saw one in foothills here at night. Almost hit it.
It was in the middle of the road and didn't move even with horns from cars from both sides.
Had to wait over 5 minutes.
Another was in CO springs. When I honked, it just looked straight at me and continued to walk in the middle of the road for few minutes.
Too bad that it was before I had any dashcams.
