Not sure why this will wind people up. I work in transport and a former colleague moved to a flying car company. They went bust. It's niche/novelty or for those who don't know what to do with their money. It won't be mainstream. Whereas cycling is an excellent solution for many people's transport needs in urban areas.
Yes you can. Though there has been a distinct lack of them of late. Also part of me is drawn now to the allure of a larger house in West Dulwich where I can be link detached/semi at worst. The gardens are also still quite small in most of the triangle IMO.
