I don't think that's right. Because safe following distance can only prevent you from slamming into the car in front of you if it breaks hard. If it hits something and stops way before the breaking distance, there's little you can do.
There was something you could have done: leave more space.
It is physically impossible for a car to come to an instantaneous stop for no reason. It would have to e.g. drive into a concrete wall, but if there's a wall across the freeway you should've seen that from afar.
You only really need to have enough distance to be able to notice the car ahead braking and start braking yourself.
That is your opinion, and my local DMV does not specify a distance that long.
Well "unsafe lane change" can be totally legit as well. I for once had to do no think abrupt lane change when I saw some largish object appear seemingly out of nowhere and it was flying towards my front window. Still do not know what it was. Abrupt lane change did not cause any problem in this case but in theory it could have.
Of no fault of their own, the car you hit trying to avoid something means you didn't avoid them. The car you hit did nothing wrong, but you did. Insurance will place you at fault at a minimum of partial fault. You will not be blameless in your example if you do hit someone/something
I am not expecting anything. Just trying to save my life.
I have better solution. Why don't we stop manufacturing cars. No more car crash victims.
Growing up in the Midwest, I remember being taught (not sure if this was official or something I got from my father, older brother, or maybe an uncle) to quickly assess if I believed that I would hit the deer or not.
If I was going to hit the deer, regardless of my actions, I was to accelerate into it.
If I could brake and avoid it, I was to brake.
I've been in that situation a few times. In the case of a collision with a deer, I accelerated into it and only took damage to the front passenger side panel. I do believe that it helped prevent a bad situation from becoming worse.
In the other cases, I was able to avoid a collision by braking.
Later in life, I did swerve once to avoid a large animal that I mistook for a person walking on a very dark, very rural road. My car flipped and slid on it's top ~100 ft. before coming to a stop. Myself and all 3 passengers walked away without incident but I still feel fortunate that we all did these many years later. Swerving is almost always the wrong answer.
Reason given was that braking causes the front end to drop causing the deer to be “pushed” up onto the hood and into your windshield.
No sure if this is true or not.
