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.
Fiat's autonomous emergency braking system, dubbed City Brake Control, is an urban low-speed crash avoidance system that works between 5 and 30 km/h. It was first made available as an option on the third generation Panda; it was also made available on the 500L and its variants.
