National Highways Authority Of India [NHAI] — Fastag lane used by other commuters, where is the preference for tag holders?

Address:

560076

I have been using Fastag for some time now and recently (24th Dec), I passed through few toll plaza on Bangalore-Mangalore highway. I was surprised to see the Fastag lane being used by all passengers and I had to wait in the queue for long to pass through. Even the toll plaza people say "there is too much rush, so we allow them", this is really crazy.
So, what is the point of having Fastag when we don't get preference. I think NHAI should take action to ensure ALL the toll plaza allows only tag holders in the dedicated lane. Otherwise, I see not many will take advantage of this.
Please strictly instruct all toll plaza people to take necessary action immediately.
