Instead of making a Saturday trip to change an oil and chat with mechanics about good old days, about whether, girls, beer, or whatever it is, I am sure better staying home to chat on Facebook, while my car gets oil change on its own. If that's how you prefer it, that's fine. But all my mechanic ever chats with me about is about how much I need his $49.99 radiator purge. It's not how I want to spend my time. If its going to be safe, noone will need to be convinced. Many people have an innate fear of things they can't control. Think about all the people who fear flying on commercial airliners -- quoting them a statistic about its safety doesn't make their fear go away. There will need to be a lot of convincing.
