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 new model also comes standard with all-wheel drive. The Model S 85 offers a more powerful 362-horsepower motor, adding an 85 kWh battery pack that extends the range to 265 miles. The Model S 85 is now the only rear-wheel-drive Tesla, as the others have moved to all-wheel drive and a dual-motor system. The Model S 85D boasts 422 horsepower and a range of 270 miles.
