The rise is quite considerable as it equates to £2.00 per day for those who make return journeys. I was always happy to pay the £0.12 or £0.24 for a return journey, As much as it helped clear out loose change but £2.00 per day may well force me onto the Motorway and go round contributing to the traffic across Barton bridge.
Now a rise to £0.20 per trip would work. I am also skeptical when they say long queues. I cannot ever remember being behind more that 10 cars in all the years i have used the route.
Automated means doing a couple of guys out of a job as well so everybody loses all ways around.
