I must respectfully disagree with the comparison. These are unrelated problems with completely different dependencies and requirements. Automating a rail system involves integrating complex infrastructure and safety systems, which can be prohibitively expensive and technically demanding. In contrast, developing self-driving cars, while challenging, is a more contained and potentially achievable problem, often requiring less extensive infrastructure changes. For instance, IT students can set up a self-driving car with minimal equipment, whereas automating a basic rail system setup would be out of scope for most people. Additionally, the article underestimates advancements in self-driving car technology and overlooks the unique challenges of upgrading legacy rail systems. Furthermore, the comparison fails to account for the different regulatory landscapes and safety standards impacting the feasibility of implementing autonomous systems in each domain.
