Step-by-step explanation:
Government regulations, such as laws requiring seat belts in new cars, have played a significant role in the development and widespread adoption of seat-belt technology. These regulations have helped to create a market demand for seat belts and have incentivized car manufacturers to invest in research and development to improve the design and effectiveness of seat belts.
