![Easily win the Tour de France every year thanks to this bicycle secret: there’s no law that says you CAN’T enter the race with multiple people on a bike! [*]](https://worstplans.com/wp-content/uploads/2018/08/1-bikes-all.png?w=1024)
[*] But you would be disqualified from the race. Background: Bicycle races have stagnated due to their archaic one-rider-per-bike format.

Background: Certain types of vending machines are capable of squeezing oranges and dispensing the freshly-squeezed orange juice right there at the machine. Generally speaking, these machines actually show you the oranges through a transparent window, so you can see the orange-juice-making process. Most of these machines proclaim that you are getting “100% Orange Juice” or…

Background: Running a business is expensive, and employee wages are usually a huge fraction of total costs (see Figure 1). However, these jobs can’t always be eliminated: many jobs still REQUIRE a human employee, and jobs that require an on-site presence can’t be outsourced. Proposal: Some jobs require an on-site presence and are difficult to…
