I also have an idea that is beyond my ability to create. I would like to invent a cycling jersey that will make the wearer of the jersey appear to be bigger than he/she really is. When a driver of a car is 100 yards or more behind the cyclist in my jersey, the cyclist would appear somewhat in the way of the driver. As a result, hopefully, the driver will veer away from the path of the cyclist a bit more than usual. At 20 yards or less the cyclist will appear normal to the motorist.

The chance of a cyclist getting hit from behind by a car is less than the chance of most other cycling accidents, but a newbie cyclist wouldn't know this fact. For this reason my cycling jersey would almost sell itself.
