At least we behave like them sometimes. Let me give you an example:
Summary: Some automakers don’t install dipsticks anymore, because car owners don’t use them. Two reasons why those car owners are stupid:
1) Cars are the third most expensive investment of their lifes (behind houses and children). If they destroy the engine, they destroy a huge amount of their (hopefully) hard earned money
2) Should you trust computers to check the oil level for you? Computers may not work properly sometimes. The dipstick works everytime.
