Here are some short videos I found from Youtube that clearly to understand, what do the car owners think, why and how they modified their cars.
The 4 starting point that I have presented in the week 3 are Magic, Travels, War and Cars. It was really difficult to decided which topic is the most suitable for me to explore in depth, although I personally perfer Cars. This theme I can get more relevant information from the Internet and books, which will help me better understand the theme. And I think that cars have become a part of people's lives and human culture. More people should to understand such a creation of human wisdom, not just as ordinary mechanical mobile tools. Of course, Adam gave me some suggestions that the “Car” contains too much and wide range scope. It should be narrowed properly. So I tried to turn cars to “motor sport”, but this theme is still widespread.Therefore, I selected "car modification" as the starting point to explore in depth.
Car modification (or car tuning) is to modify the performance or appearance of a vehicle. Modification, has become a way to personalize the characteristics of a car to the owner's preference. Cars may be altered to provide better fuel economy, produce more power, or provide better handling and driving experience.
Car tuning is related to motor racing, although most performance cars never compete. Tuned cars are built for the pleasure of owning and driving. Exterior modifications include changing the aerodynamic characteristics of the car by side skirts, front and rear bumpers, spoilers, splitters, air vents and lightweight wheels.
