It's a feature you'd never expect to see installed inside of a car.
Phil Weicker and Duncan Forster have morphed their 1969 Cadillac Coupe DeVille into a fully functioning mobile hot tub.
They plan to use it to set the land speed record for the world's fastest hot tub.
The two car enthusiasts from Los Angeles, both engineers, have nicknamed the vehicle the "Carpool DeVille," according to Barcroft TV.
The project is based off a prototype they created while students in Canada.
The mobile hot-tub, which bubbles as they cruise down the street, was installed over a period of six years.
Weicker and Forster purchased the vehicle for $800.
They modified the car to adjust the suspension, install the pool plumbing and improve its heating.
Individuals commenting on the Barcroft TV's video documenting the car appear impressed.
"This is amazing," one individual commented.
"That's awesome," echoed someone else.
Now that's what I like to call 'car pooling,'" another said.
