Recently, Tesla published a popular - science article, presenting the perspective that "a heavier car doesn't equate to greater safety." The article referenced collision research data from Tsinghua University. It highlighted that when a vehicle's mass doubles, its collision kinetic energy also doubles. This results in a 100% increase in the potential for harm outside the vehicle, while only enhancing the protection for occupants inside the vehicle by approximately 16%. This data clearly shows that the harm stemming from the increased collision kinetic energy far outweighs the limited protection that the vehicle's added weight can offer.

Moreover, an increase in a vehicle's weight can lead to several issues. Brake components are more likely to overheat and wear out. Tire wear is also exacerbated, which in turn drives up maintenance costs. Tesla's initiative here is aimed at justifying its lightweight technology strategy, stressing the concept of "shedding unnecessary weight and maximizing safety."
