In reality the sensor head of the Fennek (Strider) is retractable (watch 5:25: http://www.youtube.com/watch?v=Hw2vkzS2ir0.
This makes reconnaissance far more easy as you can drive behind trees, a small hill or any other kind of cover and still scan the area with the extended sensor head.
Integrating this feature would be nice as it makes the "boring" reconnaisance work more interesting and powerful and potentially leads to more and better teamplay.
