Deer on the road is an edge case that humans cannot handle well. In general every option other than hitting the deer is overall worse - which is why most insurance companies won't increase your rates if you hit a deer and file a claim for repairs.
The only way to not hit/kill hundreds of deer (thousands? I don't know the number) every year is to reduce rural speed limits to unreasonably slow speeds. Deer jump out of dark places right in front of cars all the time - the only option to avoid it that might work is either drive in the other lanes (which sometimes means into an oncoming car), or into the ditch (you have no clue what might be there - if you are lucky the car just rolls, but there could be large rocks or strong fence posts and the car stops instantly. Note that this all happens fast, you can't think you only get to react. Drivers in rural areas are taught to hit the brakes and maintain their lane.
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.
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.
