floatboat

A luxury sedan that prioritizes comfort over handling and performance. Used in a derogatory way by fans of sports sedans, which are the opposite.

Float: The objective of this type of cars is to isolate the driver from the road, which makes them feel like they "float" above it.
Boat: Because handling is not the priority, they can be hard to maneuver, a characteristic they share with actual boats.

These cars are typically preferred by older people because they offer a relaxing ride, whereas younger people prefer sport sedans for being more fun to drive.

Dad, your old Caddy is such a floatboat. When I drive it, it's hard not to fall asleep. My new Mercedes is so much better
