Definitely not. But it's not just only optimizing for life, it's having flexible and reliable transportation while making sure as few injuries happen as possible in the process. Motor travel let us distribute food, medicine, and specialized labor that would otherwise be impossible/impractical to do. Sure you can argue that's not worth the non zero number of lives lost in the process, but we wouldn't be able to live the modern lifestyles we have today without it. Like being able to go to a hospital filled with teams of experienced specialists to get better treatment.
