Gas Gauge Arrow
How often have you driven up to the gas pump wondering on which side of the vehicle the cap is situated? Well eventually, only in the last decade, car manufacturers have put an indicator next to the fuel gauge – an arrow that points to the side of the car with the cap. Brilliant! This will stop you from peering at your rearview mirrors desperately as you begin pulling next to a gas pump and save you from having to drive your car around to the perfect position.
Holes In Pen Caps
You may have previously decided pen caps are practically useless considered they usually have a large hole in them. However, there is actually an extremely crucial function behind the design of these caps. After the caps were accidentally swallowed a number of times, they added the holes which serve the important purpose of allowing airflow in such a daunting situation. You can be sure that countless children (and adults) have been saved from suffocation and choking thanks to this ingenious detail.
