Strange question for you guys regarding wheel offset.

Am I right in thinking the higher the offset + the more it points to the shocks and the closer to 0 the straighter the wheel is to the hub and the lower it is in - the more it aims from the car?

If the above is correct here my strange question lol.

Why doesn't people just run as high as offset as thay can then since to my untrained eye this just looks like adding more negative camber but is see thing like I need a lower offset for better handling?

Please explain!
