BMW came up with a plan to deal with Los Angeles' soul-sucking traffic problem: self-driving submarines that commute down the Los Angeles River.

Designers with BMW came up with the idea for the Los Angeles Auto Show's Design Challenge , which asked designers to use a natural phenomenon to solve a human problem. In this case, the designers were inspired by bioluminescent jellyfish. The team designed Mini Cooper pods that would be propelled by hydrogen fuel that is created by bacteria when salt and fresh water mix, according to Gizmodo.

The pods would travel down the Los Angeles River and all its tributaries kind of like mini-subway lines. Gizmodo explains:

The other key part of BMW Designworks' proposal is taking the L.A. River and other tributaries and filling them with enough water so these little submarines can travel around the city on these newly created "subways." In the winter the water does flow tremendously deep through these channels, so they reasoned that flooding the channels permanently would create a dual benefit of replenishing L.A.'s groundwater and preventing billions of gallons of stormwater from flowing directly into the ocean.

In a way, this fantastical idea makes some sense. Before there was Waze, the Los Angeles River was the preferred route for bored teenagers and anti-heroes to escape traffic:

We're curious just how commuters would head back upstream at the end of the day—maybe there's a salmon-inspired design in the works?
