Business people are often very busy, and sometimes there may be work to do even in the car. However, when sitting in the car, it's inconvenient to write something down. This is where the steering wheel tray comes in handy. This tray is custom-designed based on the steering wheel. Once placed on the steering wheel, it becomes a small desk, allowing you to write things down without any issues. In the morning, if you're running late while driving to work, you can place the food you've bought on this tray and eat conveniently. Of course, you should not use this tray while driving, as it could still be dangerous. It currently sells for about $25 abroad.
