In the interests of objective analysis and science, I am now very curious about what the lag is if any between a steering wheel command from an SUV of the type driven by Ms. Good, and when and how long the vehicle actually starts to change direction.
I don't have an SUV so I can't participate but maybe some of you all could and bring back your data.
It seems to me if my steering wheel is cranked hard in one direction (i.e. towards the ICE officer) and then while attempting to move forward, I crank the wheel hard to the other direction (i.e away from the officer, assuming that's what happened), that obviously doesn't mean the actual direction of travel of the SUV is going to immediately change as if it were a dragonfly flitting about.
As I seem to recall from experience,your vehicle will initially continue in the original direction of travel for some distance until the steering wheel command has been transmitted to the wheels. Additionally, when making maneuvers like this, vehicles will tend to make a "circular" sort of motion.
But try it with your dog, spouse, or child and get back to us.
Put someone you love directly in front of your SUV with your wheel cranked to the hard left and the loved one a foot or two in front of your vehicle. Step on the gas, then while accelerating from a stopped position, immediately crank your wheel hard to the other direction.
Would you bet money that you won't hit the loved one standing in front of your vehicle?
I guess that's what Ms. Good did.
No, actually, she bet her life.
Not a good wager.

In reading a little more about the technical aspects of how steering systems on automobiles work, there are a number of reasons that could contribute to a lag between steering wheel inputs and the vehicle's response.
It can depend on how the steering wheel linkage etc. are constructed. It can also vary depending on maintenance issues and wear and tear in the steering box and other components as well as things like the condition of the tires, alignment, and so forth.
Assuming the SUV is still driveable, one would hope that a comprehensive forensic analysis would include actually test-driving the vehicle to try to determine these characteristics of this vehicle.
Having said all of the above, if you are ever out with your vehicle and the police tell you to stop and get out of the vehicle, but instead of doing so, you choose to flee the police and one of them happens to be directly in front of or very close to your vehicle (front, sides or rear of the vehicle for that matter), it would be a mistake to believe yourself to be Mario Andretti or Knight Rider or Speed Racer with the magical ability to operate your vehicle with the adeptness of Neo in the Matrix manipulating time and space at a whim.
In fact doing so would be sheer stupidity on your part, and you are clearly assuming the risk.

As I seem to recall from experience,your vehicle will initially continue in the original direction of travel for some distance until the steering wheel command has been transmitted to the wheels. It isn't a matter of time lag in the steering system. Steering response is usually close to instant. The delay comes from inertia. The more mass, the greater the velocity, the more inertia the front wheels need to overcome to change the direction of the car. As the car in this case was barely moving, there is relatively little inertia to overcome, in spite of the mass of an SUV.
Here's a good demonstration of car inertia. Watch the wheels turn, before the car responds. Of course, the car in the incident was not going anywhere near the speed of the cars in this demonstration.

Steve,
A car "barely in motion" has lots of inertia.
If the car was "barely moving," then trying to get it to change direction is very very difficult.
Anyone who has driven a car knows that.
You have to get up a little speed before you can actually get the vehicle to turn.
Especially a big heavy vehicle like an SUV.
So, if the car in the incident was traveling much slower than your youtube clip, it would have been LESS responsive, not MORE responsive.

A car "barely in motion" has lots of inertia.ummm...no. Recall the formula for kinetic energy E=1/2M(V squared)
Recall the definition of inertia:
in·er·tia/iˈnərSHə/noun
noun: inertia
1. a tendency to do nothing or to remain unchanged.
2.Physics a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.Inertia is the tendency to keep doing what it is doing: either sitting stationary, or in motion in a particular direction, at a particular velocity.
Inertia of a moving body increases as the square of the velocity, so the faster a car moves, the more inertia the steering wheels, or brakes, need to overcome.
The national news ran the video from the officer's cell phone. Yes, it looks like the officer may well have been clipped by the car. If he had been hit hard, he would not have gotten the two later shots off, because he would have been on the ground. Reportedly, the officer has 20 years experience. Seems that, somewhere along that time, he would have been trained to instinctively get out of the way of the car, because killing the driver will not stop the car, as he proved.
More striking is the video of the driver. She does not look like the wild-eyed "terrorist" the regime is describing. Everything was fine, until her interaction with the two officers who got out of the pickup, went tragically wrong.
Cell phone footage raises new questions about ICE agent’s tactics before fatal shootinghttps://www.yahoo.com/news/articles/cell-phone-foo...I take it as a given that, as the FBI is keeping all the evidence to itself, we will only see evidence that buttresses the regime's narrative.

Steve,
It's rather obvious that you don't drive, or if you do, you're not a very good driver and don't drive very much.
You also don't know anything about physics.
Inertia has nothing to do with kinetic energy.
In any case, anyone who has ever driven a car knows that when the car is motionless, it is MUCH more difficult to turn the steering wheel.
Ergo, you don't drive.

Was crossing the street once and a woman ran the stop sign in her big SUV. I ended up holding on her hood by my fingernails. Another half second and I would've ended up under her undercarriage and had a much worse day. Fortunately she stopped.

Karen SUV drivers are also notoriously bad drivers and prone to hitting things in the first place.
One of the reasons to STOP immediately when there are any people in the vicinity, police or otherwise, is because it's very easy to misjudge and the people in the street have to "guess" your intentions as the vehicle driver--and the consequences of being wrong are often fatal.
These same lefto dum dums would be screaming in outrage if a MAGA driver accidentally hit a leftist protestor blocking or even just "protesting" in the street, especially if an officer had instructed the MAGA person to stop their car and exit it.
This is just basic safety and common sense.
These are the same leftist entitled a-holes who think they don't have to follow the rules and speed through crosswalks even if a pedestrian is present in it.
They, like Steve203, are such bad or inexperienced drivers they don't actually know how motor vehicles work in actual operation. They think cars are EASIER to turn when they are motionless, and MORE DIFFICULT to turn when they are travelling forward. That's a real tell about Steve's total lack of driving knowledge.
This idiot SUV driver was so entitled and selfish that she didn't care who she hurt or killed. As was her instigating "partner." She didn't care if she hit the cop who shot her, she didn't care if she hurt the other cop reaching for the driver's door, she only cared about herself and her delusional leftism. A sane effing driver would have immediately stopped when she saw the cop standing right in front of her, regardless of whether she heard the command to stop (which she obviously must have).
They keep saying she's a mom of 3 kids. Yeah what a great mom that the father of her two older children has custody of them, not her. What a great caring person this must be.

Marco, we have had some useful discussions, but this isn't one of them. Turning the steering wheel, in a car without power steering, is harder when the car is stationary. The car's inertia wrt changing direction or speed of travel, while in motion, or not, is an entirely different matter. By the way, Honda Pilots have power steering as standard equipment. With power steering, it's easy to turn the wheel at any speed, including zero.
Steve...took both high school and college level physics.
from the net sifter:
Linear kinetic energy (\(K=\frac{1}{2}mv^{2}\)) relates to inertia (mass, \(m\)) as a measure of motion resistance, but inertia's most direct parallel is rotational inertia (moment of inertia, \(I\)), where \(I\) replaces mass (\(m\)) in the kinetic energy formula (\(K_{rot}=\frac{1}{2}I\omega ^{2}\)), showing that rotational kinetic energy also depends on mass distribution (\(I=\sum mr^{2}\)) and angular velocity (\(\omega \)), not just total mass. Essentially, both linear and rotational kinetic energy show how an object's mass (or mass distribution) resists changes in motion (velocity vs. angular velocity).
Key Relationships
Linear Inertia (Mass, \(m\)): The resistance of an object to changes in its linear velocity (speeding up/slowing down).
Linear Kinetic Energy (\(K_{trans}\)): \(K_{trans}=\frac{1}{2}mv^{2}\), where \(m\) is mass and \(v\) is linear velocity.
Rotational Inertia (Moment of Inertia, \(I\)): The resistance of an object to changes in its angular velocity (spinning faster/slower). It depends on total mass and how that mass is spread out from the axis of rotation (\(I=\sum mr^{2}\)).
Rotational Kinetic Energy (\(K_{rot}\)): \(K_{rot}=\frac{1}{2}I\omega ^{2}\), where \(I\) is rotational inertia and \(\omega \) is angular velocity.
How They Connect
Analogy: \(I\) (rotational inertia) is the rotational equivalent of \(m\) (linear inertia).
Calculation: Rotational kinetic energy is derived by summing the kinetic energy (\(1/2mv^{2}\)) of all tiny mass elements (\(dm\)) in a rotating object, substituting \(v=r\omega \), and recognizing that \(\sum mr^{2}\) equals \(I\).
Example: A hollow cylinder (high \(I\) for its mass) spins slower than a solid cylinder (low \(I\) for its mass) at the same energy level, demonstrating how mass distribution (inertia) affects motion.
In short, linear kinetic energy uses mass as the inertia factor, while rotational kinetic energy uses moment of inertia, which incorporates mass and its radial distribution relative to the axis of rotation

Exactly.
You don't drive.
