Cars might skid on wet roads because the water gets under the tires of the car. Then the cars don't have enough traction.

The technical term is 'aquaplaning' or "hydroplaning".It happens because a thin film of water lifts the car's tyres off the road surface - and the vehicle loses its grip on the tarmac.
There are many places where one could see the act of hydroplaning in action. The best place to see hydroplaning in action would be on a street on a wet day and a car slides on the wet street.
I believe you mean "Why are wet roads more dangerous than dry roads to cars?"The answer is relatively simple. Safe roads have a good amount of friction in order to let the car steer safely. On a wet road, much of the friction is reduced, not only hindering steering, but rendering brakes ineffective.
If you are driving on wet roads there is no way to avoid those effects. Most brakes dry out very quickly when applied.
