The Kubernetes implementation is on the server side, not the car. The only way to control the car is through Tesla's API,[1] and that doesn't let you do dangerous stuff like turn the wheel while someone is driving.

Even if you could overwrite the software on the car, you'd still have to contend with the physical controls available to the driver. The steering wheel is physically connected to a typical rack and pinion setup. The brake pedal is physically connected to hydraulic lines just like every other car on the road. And like most cars, the brakes are more powerful than the motor.
