    Unhappy Cylinder on plane AND cylinder rotation

    I'm trying to put together some sort of design for a car-counter/rolling speed bump. (see PNG)
    At this point, the tire is coming into contact with the road and moving forward, but it doesn't recognize the rod nor turn that rod.
    Is it possible to make the tire roll over the road AND the rod and then continue on the other side of the road?

    We really appreciate any help by Saturday, January 10.

    Try making the surface your tire is rolling on one continuous surface (not two different pieces) and use a transitional constraint.

    The problem is that it in order for the rod to be able to rotate, it has to be separate from the road plane. Is there a way it can run along the road, the over the road, then along the road again?

    Try making a surface w/bump that matches the roller exactly and changing it to glass for the material. Leave what you have in place but constrain to the "glass". The tire will follow it and the roller can still do what ever you need it to.

    That is a creative suggestion, but how would that allow the tire to rotate the rod?

    Which way do you think the rod is going to rotate? I think it will rotate CW if it rotates at all when the front wheel of a rear wheel drive car goes over it. You could do a driven constraint to make the rod rotate as the wheel cross over it. Obviously this is faking what would actually happen but I don't see any clear way to do it any another way at this point.
