UnitySteer - Increase turning angle

I am building some pits for my racing game. When I enter the pits, I send 4 mechanics each to one wheel of the car. The problem is the one mechanic always gets stuck (the one going to the rear right tyre). He just runs into the vehicle, he doesn't really go around it. He has RadarPing, Autonomous Vehicle, SteerForNeighbourAvoidance, SteerForSphericalObstacleAvoidance and is using SteerForTarget to get to the side of the tyre.

I've tried almost every setting I can. Is there any way to make him turn sharper to get around the vehicle?

This is a screenshot of the mechanic running for the right rear tyre, he just gets stuck there.
