It would be a nightmare of weaving cars as people who wanted
to/didn't want to pay cash realised they were in the wrong lane

None of this was a problem when the choice was Dart-tag or cash.

that's because there were no special lanes for dart tag

you just drove though a normal booth and the barrier opened without
you paying

You could do that today using ANPR for those regular users with an
account.

1) you'd still need the barrier so that it could remain closed until
the cash payer had paid the correct amount (and in the completely idiot
proof system - received their change)

No physical barrier required, just traffic lights.

2) how do you determine which punters in the queue are going to post
pay by internet?

By concluding that all those who didn't pay, and didn't have a prepay
account, must be post-pay. Exactly the same as today (apart from the
cash/card payers).

but that will still result in a queue

It's not exactly the same as today, as today you don't have to control a
little red/green light for people to proceed

Only for a couple of lanes, and last time I drove over the bridge it was
stop/start the whole way, so this "freeflow" thing is a bit of a myth.

It is the same because you could dispense with the lights and go after
the people who need to post-pay, just like today.

just over the bridge?

Before they introduced free flow the stop-start started at the approach to
Junction 28
