Coming from a fine art/design and industial design background, I notice a lot of little things that most people would never notice.
Just the other day I was following a 2006-2011 Toyota Camry and found myself getting worked up and bothered because the bottom of the tail lights change angle between the fender and the trunk. The difference is very small (about 4 deg), but that is the biggest problem. In design, one of the worst offenses is to have something a little off like this, because it just looks like a mistake. In this case, they should have made the line perfectly straight or dramatically change the angle.
Now for the big one that has bothered me for at least 10 years...the logos on the back of the Toyota FJ Cruiser. The chrome logo on the car and the logo on the spare tire cover don't match at all as illustrated by the picture below. The angles on the 'F' and 'J' on the car are off by about 9° and the angles on the tire cover are off by about 21°. You can also see that the width of the letters is way off.
I could almost accept stuff like this on a handmade supercar, but we expect more from our mass produced cars, and you wouldn't expect this from a Japanese company.
Is anyone else bothered by these or others? Leave a comment with things like this that annoy you.
