Starting in 2010, all Fords will come with MyKey, a programmable system that will make seat belt warnings impossible to ignore, and will also be able to limit a vehicle's top speed and radio volume. Obviously, it's designed so parents can keep young drivers in check, and I can't imagine too many teens are going to love the idea. But given that most kids don't get to tell their folks what kind of car to buy, I think this could be a great selling point for Ford. What do you think? Is MyKey a good idea?
