Off the back of the discussion on M5 East now charging tolls, has anyone calculated the cost vs time saving benefits of using their usual toll roads?
and how much time do you need to be saving to justify paying for a toll road?
E.g. Lane Cove tunnel ($3.35) takes me 3.5mins to cross, but if I take lane cove rd without traffic, it'll take me 7mins. I'm willing to pay $1 for every 1 min saved with 2 people in the car, so I only take the LC tunnel when I expect there to be traffic on lane cove rd.
EDIT: I just remembered google maps already does the calculations, so my first question is pointless.
As a general rule I'll take any toll road if it saves me waiting for traffic lights.
