@Dashrender Interesting. I wonder if the same logic works with chickens. (investigating for backyard egg production purposes)
The same logic will work on almost any living thing. There's a good training book called Don't Shoot the dog. The lesson above is basically the book in a nutshell and the author shows how it can be applied to nearly any animal or person.
She has a story about her mother-in-law and how she was able to get the mother-in-law to stop a questioning patterned that annoyed the author.
People don't like to think of their children as pets - but if parents learned how to train an animal, they'd have an infinitely easier time training their children to act the way the parents want.
They also told me that the source information was proprietary to the supplier so that they couldn't tell me exactly where it's from, just that it's not from China. I'd be okay with it being from China, at least then orangutans wouldn't have been murdered for it.
The T-Rex is cool, but you're talking about apples to oranges here. Open vs closed (w/ AC and heat), and $50k+ vs $7k. One is clearly a summer toy that somewhat replaces a motorcycle, while the other is a sensible yet sporty all-season commuter. Personally (just my own take on it), if I were in a position and geographical location to consider/justify the T-Rex, I would buy an actual roadster and not a dressed-up 3-wheeled bike. Like I said, just my thoughts.
