AI Frequency Counter

[gregory.huizer]

There is an option to change the frequency count of AI traffic cars through "def/country/netherlands/ai/"; like below...
But is this also possible for the selection of different AI traffic trailer types?

SiiNunit
{
country_traffic_car : _nameless.info {
frequency: 1
}
}

I think I have found a solution...
By using the "attachable trailer" attribute of trucks and assigning specific trailers to certain trucks...
