A man was listening to the radio when the traffic report came on.

Theres a car driving the wrong way on the motorway, causing mayhem in both directions, the radio announcer warned. Police advise avoiding the area.

The man then realised that his wife was planning to take the motorway to an appointment, so he quickly phoned her to warn her via her in-car mobile.

Darling, please drive carefully because I just heard that theres a car heading the wrong way down the motorway, the man said when his wife picked up the phone.

Oh, I know, answered his wife. Theres not just one, theres hundreds of them.
