I discussed the point with a director of OneLogix recently - their vehicles all have e-tags. He himself does not have an e-tag and hates the system, but he avoids the highways - I told him he should use them and make it a nightmare for Sanral to get their money, as he can obviously afford it - will see if I've convinced him......
In a way I can understand businesses that use the highways a lot, getting e-tags - they would be the 1st to be targeted by Sanral collection and would be easy prey, as one "person" is responsible for the very large account.
Without big business to chase, Sanral has to chase us, for relatively small amounts and much harder to find - lekker!
