Jaguars failing

If enough people are doing something that they thought was logical that ends up ruining the product, I usually consider that a design shortcoming.

This was actually considered a design enhancement originally. The idea was if the screws are painted a color code, then it will be LESS likely that teams will accidentally wire them up backward and set fire to them. But what if a team fully removes the screws and replaces them in the wrong place... then the color code is misleading. Ok... make the screws retained so that they won't be easily removed all the way, thus helping to ensure the color code stays correct.

After a year of teams overpowering the retention, TI must have decided that if teams are going to take them out anyway, the may as well not have metal shavings inside on top of the possible bad color coding.

Essentially, what was intended to help teams, only hurt them more since they didn't follow instructions.
