Narrative:
I instructed the C182 pilot to make a left turn-out after departure when the departure clearance was issued. He read back right turn; wind; and departed. I radar idented the aircraft and shipped him to the next controller. I then noticed the C182 turning right and an rj departing the other runway. The cessna pilot flew right through the rj's departure course and the rj advised he was deviating left due to the traffic. I think slc runs a very dangerous operation by allowing VFR aircraft to depart the airport and then cross over the entire airport to proceed wbound. It confuses pilots; as in this case; and they make mistakes putting themselves and others in danger. It is also dangerous for controllers because it is done all day long and is very easy for the controller to miss a readback and have the pilot unknowingly start the wbound turn on their own as was in this case.

Title: SLC LCL CTLR EXPERIENCED OPERROR WHEN INCORRECT READBACK WAS MISSED AND C182 DEP CROSSED PATH OF CARJ DEP FROM PARALLEL RWY.
Narrative: I INSTRUCTED THE C182 PLT TO MAKE A L TURN-OUT AFTER DEP WHEN THE DEP CLRNC WAS ISSUED. HE READ BACK R TURN; WIND; AND DEPARTED. I RADAR IDENTED THE ACFT AND SHIPPED HIM TO THE NEXT CTLR. I THEN NOTICED THE C182 TURNING R AND AN RJ DEPARTING THE OTHER RWY. THE CESSNA PLT FLEW RIGHT THROUGH THE RJ'S DEP COURSE AND THE RJ ADVISED HE WAS DEVIATING L DUE TO THE TFC. I THINK SLC RUNS A VERY DANGEROUS OP BY ALLOWING VFR ACFT TO DEPART THE ARPT AND THEN CROSS OVER THE ENTIRE ARPT TO PROCEED WBOUND. IT CONFUSES PLTS; AS IN THIS CASE; AND THEY MAKE MISTAKES PUTTING THEMSELVES AND OTHERS IN DANGER. IT IS ALSO DANGEROUS FOR CTLRS BECAUSE IT IS DONE ALL DAY LONG AND IS VERY EASY FOR THE CTLR TO MISS A READBACK AND HAVE THE PLT UNKNOWINGLY START THE WBOUND TURN ON THEIR OWN AS WAS IN THIS CASE.
