Well that was the plan (at the Dartford crossing) to ease congestion but the reality is anything but that.
How is a visitor to the UK who may well not speak English go about logging on here (or there) to pay the crossing fee, they may not be tech savvy (possible) so just forget all about the issue by the next junction.

Which begs the question - why not have barcodes on Car roofs which identifies the car owner and perhaps
could even be used as a means of making an automatic contactless payment, from the drivers preferred
method of payment; when going through toll charging roads.
Therefore making the toll booth redundant and not beholden on the driver to remember he or she went down
a toll road and needs to pay or face a fine should they forget.

Barcodes on Cars

None runner at the moment (IMO) but will no doubt be enforced once we are all chipped for our (?) protection .........
The previous system worked & works all across Europe, the sheer level of vehicles trying to cross the Thames is the problem & not the toll booths.
Vehicles going north and trying to get them through the pipe (mind you going south is not a lot better) was, and is, the problem.
Next crossing going north is the Blackwall that was built by the Victorians & has bends in it so the horses that it was designed for would not get to upset (so i have read)
At the very least another crossing is needed but that can has been kicked down the road for the last 30 years.
