You forget that logic has bugger all to do with what the gvmt does! If they want to toll the main artierial road in Gauteng and cause untold chaos and delay, then let them.. See how quickly they voters run off. You can give them crap housing, poor service, bad jobs, but be the cause why they spend 5 hours a day in traffic and see what happens..
A few months back there was a big accident on the M1 btwn Allendale and New Rd. I was going through to Irene from Sunninghill. Saw the back log (solid on N1 right back to Fourways offramp going west) decided to go the back roads. Old PTA, Allan Rd, back onto Old Pta through to Irene.. It took me TWO hours.. Every single road was solid, not moving. Imagine having this everyday as people try to either a: avoid the toll and use back roads (which already are clogged way before rush hour) or b: have to stop and pay a toll..
