Many people find this a good compromise between size and sensitivity. The omni-directional nature means that no matter which direction from the vehicle the AP is located, it can be found.

and a 15 dBi Directional Enclosed Yagi Antenna would be more ideal for detecting an already known AP ?

For connecting to a known AP (that you own or have permission to be using) a yagi will give you a stronger signal strength. It is a directional antenna, so it has to be physically pointed at the AP.

Would it be ridiculous to say that some dude would have to bring their Hummer up onto my front lawn to detect a decent signal strenght for my AP or can they sit accross the street? or Down the street? What?

Well for an example, I can detect my AP in the
basement of my house about 300 feet away from my house. Of course this is with kismet since broadcast replys are disabled and WEP and mac filtering are enabled. I have used my AP parked across the street from my house... so it is safe to assume that someone would not have to drive onto your lawn to mooch a conection. Of course, with a properly secured AP I don't worry about something like that happening.
