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.
This article is not 100 percent true. An emergency brake can be used for a parking brake, but a parking brake cannot be used for an emergency brake. An emergency brake comes on gradually as you pull the lever (or push the pedal). A parking brake comes on all at once and locks the wheels, very dangerously.
