Sanral said 300 000 people had taken up the 60% discount on historic e-toll debt before the discount expired at midnight on 2 May, but it declined to say how much revenue was collected. If the Organisation Undoing Tax Abuse (Outa) is to be believed, however, anything short of R2.5bn collected will still mean the “system will have only pushed compliance up to roughly 50%. This in itself will be seen as a significant failure for the user-pays scheme. International evidence shows that these schemes fail when compliance drops [below 80%]”, Africa News Agency reported. More than 2.5m motorists use the Gauteng freeway each month.
