In theory, no object with mass can reach or exceed the speed of light in a vacuum, which is approximately 299,792,458 meters per second. As an object with mass approaches the speed of light, its relativistic mass increases, requiring more and more energy to accelerate it further. According to Albert Einstein's theory of relativity, it would take an infinite amount of energy to accelerate an object with mass to the speed of light.
Even if we assume a hypothetical scenario where a car could continuously accelerate without any limitations, it would still never reach the speed of light. As the car approaches the speed of light, its relativistic mass would increase to the point where the energy required to accelerate it further becomes practically infinite.
Additionally, from a practical standpoint, achieving speeds close to the speed of light would require technologies and energy sources far beyond our current capabilities. So while the speed of light serves as a fundamental limit, it is highly improbable that a car or any other macroscopic object could ever reach or exceed that speed.
