I have noticed a dangerous design flaw perpetrated by most...

Dear Tom and Ray:
Orlando
RAY: Since the Germans and Japanese started it, I'd have to assume they're trying to get even for World War II. They're probably snickering everytime you impale yourself on that key, Orlando.
TOM: Actually, the real reason is security. Our Director of Lock, Key, and Banjo Studies, Paul Silvius, tells us that in the old days, most car keys had about six "cuts," or protrusions. Now, the average is eight to ten, which means the locks are harder to pick. Plus, there are more possible combinations to choose from, so it's less likely that someone else's key will work on your car.
RAY: Of course, that's more or less irrelevant these days, since lock smiths are the only ones who pick locks anymore. Car theives tend to just break the window, since it's a lot faster and requires less skill.
TOM: But aside from the security issue, we've also noticed that there's definitely a "prestige" factor involved. That is, the more expensive the car, the more substantial the key is expected to be. We recently drove an Infiniti J-30 luxury sedan, and that key was not only huge, but it felt like it weighed about two and a half pounds.
RAY: And I think when people pay a lot of money for a car, they expect an equally substantial key. So I guess it's our own fault, Orlando. This is what we get for our "bigger is better" mentality; poked in the privates.
