Hydrocephalus is due to a problem with the flow of the fluid that surrounds the brain. This fluid is called the cerebrospinal fluid, or CSF. The fluid surrounds the brain and spinal cord and helps cushion the brain. CSF normally moves through the brain and the spinal cord and is soaked into the bloodstream. The flow of CSF is blocked.
The Tesla Model S has a collision avoidance assist system that automatically engages the brakes to reduce the impact of a frontal collision. Automatic emergency braking will stop applying the brakes when the driver presses the accelerator pedal, the brake pedal, or sharply turns the steering wheel.
Because most modern braking systems have failsafe measures and warning systems, such as on-dash brake-warning lights and low-fluid sensors, the emergency brake is most often used as a parking brake device. But the e-brake is called an emergency brake for a reason -- using it can save your life.
