Mike,
That's what I found as an interim solution.
Each object knows its shape and draws it.
Sensors first find the objects in their surroundings (which is greater than their SensingCoverage) and then ask the object if any part of their area hits the sensor coverage area.
But you know its not a good solution given the Mason classes.
 
I expect that Continous2D should provide some methods for that reason.
For example when we add an object to Continous2D we should be able to insert its Shape as well.
Thus the methods like getObjectsExactlyWithinDistance would return objects not only by their central coordinations but their Shapes.
This would be a more nice solution.
And I think many Mason users would like it.
 
Thank you for the suggestion again.

Murat -
 Here's an alternative thought that you might find simpler than
JTS - why not store the area of the object (car, bus) as a property
of the object and have the sensor query this property and "respond"
appropriately?
