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.
That means the Model S offers not only the smooth, quiet power of electric drive but the simplicity and zero-emissions status of a battery electric car. For the Performance edition with the largest battery pack, Tesla quotes acceleration of 0 to 60 mph in less than 5 seconds, and a top speed over 100 mph.
