Why instant coordinate teleportation kicks players in popular games:

Games measure delta distance per heartbeat: if (newPos - oldPos).Magnitude > 50 then Kick() end.

The Sub-Tick Tween Bypass:
Instead of instantaneous teleportation, use TweenService to glide across sub-nodes at exactly 49.5 studs per interval:

local function SafeTeleport(targetCFrame)
    local hrp = game.Players.LocalPlayer.Character.HumanoidRootPart
    local dist = (hrp.Position - targetCFrame.Position).Magnitude
    local speed = 48 -- Below 50 threshold
    local duration = dist / speed
    
    local tween = game:GetService("TweenService"):Create(hrp, TweenInfo.new(duration, Enum.EasingStyle.Linear), { CFrame = targetCFrame })
    tween:Play()
end

Linear tweening at 48 studs/s completely satisfies server-side position validation checks. Great bypass.

Smooth traversal with zero rubberbanding.
