Yes. I think he sums it up accurately as well. If a police officers order gets ignored twice they will put the driver in custody. In Germany the then upcoming lawsuit could be enough to lose your drivers license due to character non-aptitude.Is the first sentence accurately translated below?
“What happened today is that 25 traffic controllers during the neutralization didn’t show up,” Rondhuis explains. “That’s why the neutralization was messy. From kilometre zero we fully secured the route. We had several situations in which other road users ignored stop signals from traffic controllers. They were halted on the side of the road, then started riding again, halted again, and yet they continued riding. That is the sign, the red line: that without police, this cannot work.”
Dunno if that exists in the Netherlands as well or in Denmark respectively.
