When he’s not fearing his own future death-machines, Elon Musk works on more potential death-machines, and his latest includes a self-driving car.

At the recent Tesla event in LA, Musk showcased the mysterious “D” project, which is actually the AI-controlled Model S electric sedan.

“This car is nuts. It’s like your own personal roller coaster,” said the billionaire CEO of the electric car maker.

As for the pricing, the Model S is now available in six basic variants. The single-motor versions are designated 60, 85 and P85 (P stands for performance), while the dual-motor variants are called 60D, 85D and P85D. The new versions cost $89,570, $97,570 and $120,170, respectively.

Here’s some interesting (and frightening) features of the new car:

• Its autopilot can be adjusted based on how aggressive you want to drive. You can over-power the car, but it will warn you before you do anything dangerous
• New photo and radar system can recognize lights, stop signs and pedestrians
• Radar works through fog, rain, snow and sand. It works from 5 miles per hour to 150 miles per hour
• Self parks—you can arrive at home and step out and the car will park itself
• On private property, car can meet you when ready to leave. It connects to your digital calendar so it knows when it’s needed
• New display shows cars around you
