I tried to solve it by creating a trumpet intersection but it's not working.

The logic is as follows: the driver has the chance to stay on the highway to enter the city through the main avenue or take the access ramp to enter the city through the other avenues but no one is taking that route, even if the destination is a building near or on the avenues closer to the coast.

Did I do something wrong or is the AI ​​of this game stupid?
