Design Proposal for an Armoured and Adventure-Ready Tesla Roadster

Design Requirement:

‘To transform the Tesla Roadster into an extreme sports adventure vehicle capable of withstanding hostile environments and attacks. The vehicle must be equipped with a surface material that is not only bulletproof but also resistant to various forms of physical assault, including impacts from metal bats, crowbars, axes, rocks, and other weapons.

Reinforced windows and headlights with equivalent protective capabilities are required. Additionally, the vehicle should feature airless tires designed to resist punctures and slashes effectively.

While enhancing protective measures, the vehicle must maintain or improve upon existing safety features, such as crumple zones, to ensure passenger safety during collisions. The integration of artificial intelligence is encouraged to assist in material selection, structural design, and adaptive safety features, drawing upon advancements in materials science, mechanical engineering, aerospace engineering, and related disciplines.’
