A ban on car traffic for countries

[valera_t]

A ban on car traffic for countries
does not work on all of 100%.
Sometimes still appears on the roads of the country, rare, but does occur.
What is the reason?



example:

file def/country/poland/ai/zil433.sii

SiiNunit
{
country_traffic_car : _nameless.info {
frequency: 0
}
}
