In response to deteriorating manners and an increase in injuries on trains, a new law regarding boarding has been established.
1. Passengers are legally required to use a two-person passenger belt to ensure safety and decorum.
2. To ensure hands are never idle, passengers must hold onto something. One person must hold the strap; the other may hold onto their belted partner.
3. While riding, passengers must interlock their legs between their partner's legs, supporting each other to prevent falls.
It has been over five years since this law was enacted, and it has become a completely normal part of daily life for the citizens.
