Compared to driving on dry pavement, how does the braking stopping distance change when driving on wet, rain-soaked asphalt at the same speed?

1. Braking distance is reduced by 50% due to water cooling the brake discs
2. Braking distance remains exactly unchanged
3. Braking distance increases significantly, typically by 1.5 to 2 times or more
4. Braking distance only increases if the vehicle is overloaded
