It's not that easy, Peugeot. You can't just take the Captain's Holodeck, rename it the Holobench and not expect everyone to see right through you. Holobench is just one part of the Peugeot-Citroen virtual reality system designed to assist in all aspects of manufacturing and vehicular design for the French automaker.
The Cave is the first part of the system, and is probably the most fun. It is a large visualization system that includes a seating buck, or a driving console. In the most common configuration, a person will sit on the seating buck, which can be constructed to emulate any style of seating arrangement, and interact inside of the car through virtual reality. Everything from adjusting the virtual mirrors and scratching your real ass can be done while in the Cave, which has no relation to Batman.
