When your tires decide swimming sounds more fun than gripping the road.
means To skid uncontrollably on a wet road when a layer of water lifts your tires off the pavement — or, as a noun, a lightweight motorboat (or seaplane) designed to skim across the water's surface.
from Built from hydro- (Greek 'hydor,' water) plus plane, the word surfaced in the early 1900s for boats engineered to rise up and skim atop the water rather than plow through it — basically a boat that learned to ski. The verb sense we use for cars came later, borrowing that same image: a thin wedge of water gets between tire and road, and suddenly your car is skimming like a tiny, terrified hydroplane boat instead of driving.
- minimum speed
- can start around 35 mph in heavy rain
- the physics
- water wedges between tire and road, lifting you
- the fix
- ease off gas, do not brake or steer hard
- tread's job
- channels water away so rubber touches road
