    Let me say firstly I have noticed a certain trend in the attitudes towards this game, I understand it is groundbreaking and a lot of people love it
    myself included, Although...

    At risk of upsetting the fanboys and a vehicle developer, I feel it necessary to point something out.

    In regards to rollover propensity regarding the different 4x4's and lifted SUV's and throughout extensive testing of these vehicles,
    I have discovered that the D15 does not fit the classic profile of rollover risk at either 60mph or even at an incredible 115mph.
    Making it decidedly unrealistic and defying the laws of physics seemingly to satiate the wants of younger users that do not understand the handling and physical capabilities of these vehicles. I find this fairly irresponsible and lacking regard to the personal safety of younger users who may grow up one day to drive these vehicles in real life, in short this driving simulator may pose a risk contributing to the serious injuries and possible death of certain users who believe this simulation is an accurate depiction of how, especially lifted 4x4's and SUV's handle at normal highway speeds.

    Am I over-reacting, maybe, think what you want, but knowledge gained from whatever arena in regards to personal safety and that of others can be garnished in many ways from various aspects of day to day life. This is just another one. Albeit a game that's teaching kids there's nothing unsafe about going full lock to lock doing 60mph in a lifted 4x4, when exactly the opposite is true.

    Before you respond to this thread look at the pictures of the other unique vehicles. Compare them to the pics of the D15. And watch at least 7 minutes of the youtube links.

    All vehicles including the D15 were tested at 60mph with a lock to lock steering maneuver, for example swerving to miss an object in the vehicles path.

    One of these things is not like the other...

    And the D15
    First pic at 60mph, second pic 115mph almost twice the speed

    screenshot_00021.png screenshot_00017.png
    No roll over, no wheel lift even at 115mph.

    Since this simulator is trying to mimic real life as close as possible,
    Here's a couple of links about real life,

    SUVs =/= pickup trucks. SUVs are far more top-heavy, and only poorly engineered vehicles can flip on flat pavement. There are plenty of SUVs and pickup trucks that can't be flipped without actually ramping over something or catching their wheels sideways on an obstacle. Real cars don't magically grip when you flail the steering back and forth. If you steer that quickly, the front wheels lose grip, the vehicle doesn't turn, and it doesn't flip over.

    While your observation is indeed correct, making statements like this:
    Is how you do this:
    Saying that a vehicle in a game doesn't behave like it should poses a risk to the uninformed is like saying children the world over will end up stabbing each other in the eye because they've played a bit of Skyrim and thought that waving a sword about would be fun.

    Here's a stock Chevy Tahoe drifting on public streets at the limit of grip and weight transfer and not even coming close to flipping:



    You can cherrypick poorly engineered examples of cars failing the moose test all you want. That doesn't represent the vast majority of cars that get no attention because they don't flip.

    1. Please define plenty. (I'm not talking about manufacturer tests, third party testing would be desirable)

    2. No catching of tires on any obstacles same flat surface outside the walls of gridmap

    3. No flailing or quick steering, I conducted the tests using a smooth, slow, left to right (lock to lock) at 60mph

    4. The vehicles did turn and did tip/flip/roll over (apart from the D15) There's a mathematical formula in regard to vehicle height and track width.
    (it's talked about in the first youtube link)

    5. Do you personally know the Arabs in that video, can you be 100% sure there is no stability or traction control involved, how about the tires used?

    6. What would be the closest real-life counterpart to the D15, roughly what year would you say it is, and does it have traction control or stability control?

    7. Was the handling of the D15 changed at any time to "supertune" out the rollover factor?

    The d15 rolls over at way less stress and more stress than you have implemented and I think they are unrealistic tests moving down a highway then quickly moving the steering to full lock either side for no reason.

    It was built according to the construction of a real early 90s full-size pickup truck, like a Silverado or F150. No tuning was done to make it roll more or less. The lifted off-road D15 flips extremely easily on flat pavement. There is no traction or stability control because it apparently doesn't need it to avoid flipping, and it is meant to be a vehicle from the early 90s, predating the widespread use of such systems. The videos you've shown have done nothing to prove that a truck like the D15 should flip in ordinary (or even extreme) maneuvers at those speeds.

    As for stability and traction control in the Tahoe drift video: the only way you would even get a modern vehicle to slide like that would be to turn off those systems.

    Actually the point is, it doesn't. I wouldn't have bothered with this thread if it was at least somewhat true to life.

    Like I said in the above post, not steering quickly.

    Let's hope no-one accidentally pulls out in front of you, because you see no reason to avoid through the means of steering. Because emergency situations like deer, bad drivers, road debris, or any other occasion to avoid a collision seems unrealistic.

    We build things in our simulation according to real life data, not some belief that all trucks are easily-flipped deathtraps. If the vehicle doesn't flip, then it doesn't flip. I'm not going to add a 50kg ballast to the roof to satisfy someone's idea of how a vehicle should behave. Right now the tires on most of our vehicles have slightly too little grip - remedying this will make the vehicles more flippy, but not significantly.

    I probably could've come up with a better comparison, but the principle is there. You're completely forgetting that people have common sense and a sense of discretion. I'll keep it to cars then, because you clearly can't comprehend what I'm saying unless I hand it to you on a gilded platter. Growing up, I played lots of Gran Turismo (which even at the time advertised itself as "The Real Driving Simulator") and Driver. These games let me crash into things at full tilt with no repercussion. Before I could drive in real life, I had no intention of crashing into anything or performing the driving acts I did in those games because that's what they were. Games. I was fully aware that if I tried to jump a real Camaro off a real hill, Bad Things would ensue.

    One more thing, what's the motivation in showing up acting all high and mighty like you're some sort of authority on vehicular dynamics? The majority of this forum is knowledgeable about cars and driving, so you making a thread about armchair physics and SUVs rolling over is really nothing special.

    No tuning at all, never ever?. The lifted off-road D15 in fact does not flip extremely easily on flat pavement, not even at 115 mph, not even trying to steer to shift the weight as fast as possible. As for the Tahoe, you could spray the tires with diesel, or modify the suspension and wheels, increase the horsepower, etc. That jeep in the second video has both of those systems, didn't seem to help much by the look of it.

    Bone stock, full throttle, full steering lock. That's it.

    Cool. Being passive aggressive when you've revealed to everyone that you're totally incompetent is a great way to make yourself look like an even bigger asshat. Your arguments fell apart really fast in this thread; you resorted to backpedalling and personal attacks pretty quickly instead of defending your thesis and backing it up with better evidence than "hay guise look @ dese youtube vids". You're a waste of energy and clearly have nothing better to do with your time. Stay off my forum, stay off the Internet.

    Good riddance.
