Comment: A focus on self-driving cars is appropriate – this is a timely and rising technology. You give a nice comprised introduction to the technology. You also already have a good listing of potential benefits, challenges and concerns. In the next phase of work on your blog, consider if we can expect self-driving cars to become ubiquitous? Are there places where they are more appropriate or useful?
Writing: Your writing is good and indicates that you thought about requirements of blog writing (which should be clearly written, accessible, and can take a perspective). Continue like this. In a blog you do not need to use Harvard referencing style. Just add a link to the site.
Suggestions: Please be clearer about the SDGs that this technology is claimed to address – and critically assess these claims. Also consider who might be affected by the rise of self-driving cars, who might benefit. You may want to consider existing applications and examples too. Also what are implications for our models of personal mobility, will we still be owning cars or just be sharing self-driving cars. When considering governance approaches –think how should we decide on these issues, and who should be involved?
