Pagani, have you ever thought about the fact that JW is an English-speaking forum and the majority of the members can't understand Dutch
Basically the video shows 2 Belgian road-police members doing a mobile speed control and the masculine bitch (on the passenger's seat, if you're wondering which of the two I'm reffering to) is explaining that she gets a big kick out of catching as many speed offenders as possible. In other words, if everyone is keeping to the speed limit like they're supposed to, she has a really bad day.
Then, after a while, the radio station is warning drivers about the actual mobile speed control taking place and Pagani's police girlfriend gets really disappointed because after the radio warning no one is speeding anymore.
