I had a deer merrily jump along next to my car for about 25 feet while I was white knuckling the steering wheel hoping it didn't suddenly decide to become one with my vehicle.
... huh. How fast were you going? Quick check suggests if you were going 55 mph that would have been less than a third of a second.
Not that fast, pushing 20 'cause I slowed down a lot while in a 35 zone. There were two deer in addition to the one I was wanting to stay away.
I had spied them as they were crossing the road round a bend, one was already there, another in mid-cross which completed it quickly, and the third was like "wtf bro I want to be with my mum" and didn't really know how to deal with the situation. I had slowed to a not-quite-stop and decided to continue 'cause it wasn't moving, and when I started accelerating it was like "nah bro I'm going with you now you're way cooler than mum" for about three bounds before changing its mind.
