no, there should not be a need for you to "get out of a car's way" as typically there are multiple detector loops (provided you are waiting at a traffic-actuated intersection and not one that is timed) embedded in the pavement, extending at least several car-lengths back from the intersection. The tricky intersections are those where there are no visible saw-cuts in the pavement for the loops. In those instances, it's usually best to position the bike (or trike) over either the left or right tire tracks of where a car would be in the lane when trying to trigger a green light. If there are visible saw-cuts, position your wheels directly over the saw-cut. However, even then, there are occasions where the sensor is not sensitive enough to detect the bike (or trike) and you may have to wait for a car to arrive.
