16. Fake Hood Pins
Hood pins are a welcome addition if you are building a race car and are obsessed with weight savings. However, if you have a regular street car, there is no need for hood pins since the amount of weight you will save is insignificant.
You will just look silly. People will laugh at the sight of you opening your hood the old-fashioned way and then releasing the hood pins. Hood pins are double the work and no benefits for the streets.
