begin quotes:
That is correct. In the late 15th century (around 1478), Leonardo da Vinci drew up theoretical plans for a Self-Propelled Cart. Historians often call this invention the ancestor of the modern automobile.
Details of da Vinci's design:
- The Power Source: Instead of an engine, it used a clockwork-like system of coiled springs hidden inside drum casings.
- How It Moved: As the springs unwound, they pushed gears that turned the wheels. It could travel for about 40 meters.
- Programmable Steering: It had a complex set of wooden blocks and pegs placed in the gears. This let the cart steer itself in pre-set paths or turn at certain angles.
- The Purpose: Da Vinci did not design it to be a daily driver or a car for regular people. Experts believe he built it as a special stage prop to amaze royalty and guests at court festivals.
