Which the Tesla didn't do. It plowed full speed into the deer, which arguably made the collision much much worse than it could have been. I doubt the thing was programmed to maintain speed into a deer. The more likely alternative is that the FSD couldn't tell there was a deer there in the first place.
Braking dips the hood making it easier for the deer to go into the windshield. You should actually speed up right before hitting to make your hood go up and make it hopefully go under or better stay in the grill.
Doesn't this all depend on the height of your car and the condition of your shocks? Doesn't seem like a hard and fast rule. Also, you're assuming rear wheel drive. FWD does not "raise the hood" like you're playing Cruising USA.
Please show me that guideline, anywhere.

Wear gloves when they hand you that guideline because they might be pulling it out of their ass.
Maybe, but it's still the case that slowing down will impart less energy to the collision. Let up on the brake before impact if you want, but you should have been braking once you first saw the deer in the road.
Sometimes those fuckers just jump out at you at the last minute. They're not smart. But if you click the link, this one was right in the middle of the road, with that "Deer in the headlights" look. There was plenty of time to slow down before impact.
Conditions matter and your reaction should always be for the worst possible scenario (moose and snow), braking removes your ability to maneuver as well, and locking the brakes up which will almost always happen when you panic break, would be the worst scenario. If there’s snow or rain, braking again is right out.
If it jumps out and you can’t do anything but brake, you shouldn’t do that, you grip the wheel and maintain speed, and if you can punch the gas for the hood raise. But people panic and can’t think. So maintain speed, don’t panic and lock your brakes up.
You should know how to brake without causing maneuver problems (including not locking up the wheels). It is a basic skill needed for many situations. Just keep slowing down, the accelerate just before impact is something that can only be done in movies - any real world attempt will be worse - remember if you keep braking you lose momentum, so the acceleration needs to be perfectly timed or it is worse.
In this case, the deer just stood there in the road.
Any driver and any AI should be able to stop before the obstacle in that case.
Cause it could be a human, or a fallen tree instead of a deer.
You know cars have had ABS for a long time, right?
Speeding up instead of braking is fucking stupid, you're just increasing the impact force (F=(m*v)/t), and increasing the likelihood of the deer going through your windscreen and killing people.
This sounds made up
If you think physics is made up, sure...
I don't think hitting more gas is going to gently slide the 300 pound buck under my car. It's just going to increase the impact force.
Sliding the deer under your car is also really bad for you. It's going to do a lot of damage under there such as ripping break lines, destroying ball joints, or fragging your differentials. You need to safely shed as much speed as possible while maintaining your lane when about to hit a deer.
Considering suspension, if you accelerate there's a lowering of the back of the car/raising of the front.
Conversely, breaking has the opposite effect, increasing the chances of the deer rolling over your hood and through your windshield.
You'll want to minimize that, hence the acceleration.
Read the other comments in this thread for why it doesn't work like that
When you learn how to drive you'll understand why everything you're saying is nonsense.
The physics is F=(m*v)/t
I.e. the greater the velocity the greater the force of impact.
A moving vehicle in real life is a bit more complicated of an equation, factor in the car's angle towards the horizontal as you accelerate or brake, that's the original point, but whatever.
So almost zero difference. Cars do not rock back and forth like a yo-yo when they accelerate or brake.
Now factor in the difference of force between hitting something at 40 and hitting something at 80 or more.
You and that other person trying to argue this are probably the dumbest people I've ever seen on this site.

Right before hitting begin the keyword. If you can stop before hitting yes that’s ideal, but in situations where it jumps out and you can’t react. Braking during impact is the worst thing you can do.
If you think I’m saying to line it up and accelerate for 200meters, I dont know what to say about that,
This is not correct, where are you getting this from?
Dude, the article just said to hit the brakes "if you can't avoid hitting a deer", the exact scenario you described... Did you even open it?
I can see it in the headline, without opening the article
akshually that's the sorta-nonstandard text fragment that tells the browser to automatically scroll to the text, not the headline at all
Life is not an arcade game.
aight what's your strategy for hitting a giraffe, then?
I don't know, where I live giraffes are only in the zoo and thus never on the road. I'm not aware of any escaping the zoo.
I'm sure if I lived around wild deere, my training would include that, but since I don't I was able to save some time by not learning that.
What if you're driving through a zoo though?
I've never been in a zoo I'm allowed to drive more thln e wheelchair through. They may require extra training - I would not know
Same for a moose? Speed up so you clear it before gravity caves your car roof.
You maintain speed, you can’t maneuver well if braking, and as stated your hood dips while braking too which can cause worse issues.
Troll comment.
You do that - you die.
The whole premise of ABS brakes, which all cars made in North America since 2012 will have, is specifically to allow you to maintain control when you fully apply the brakes. Unless you are a professional driver or have a car without ABS, you should just fully apply the brakes in an emergency stop. Please stop telling people that fully applying the brakes will reduce manueverability when it won't for the majority of drivers in the developed world.
And if someone's vehicle doesn't have ABS, they should know how to properly brake without locking their tires, and when it won't be appropriate to use them.
That's a good strategy to ensure you die: a mooses torso is already higher than the hood of a lot of SUVs, so you're taking a moose to the face.
No, for moose you are actually supposed to swerve and risk the ditch.
