Bo and Luke are presumed dead are driving their car into the creek. But why doesn't anybody attempt to look for their bodies or pull the car out of the lake? I know you can't expect too much sense from this series, but that's too much.

Enos tried look for them but he pulled their clothes out from the lake and rosco couldnt swim and called cooters tow truck to dig them out and ambulance it showed rosco did care for the duke family despite always chasing them.

and it is kind like knight rider show when the general lee drives by itself
