What i'm implying is that the number of people inconvenienced by
making Judd St one-way (those burdened with freight, cash, infamy,
etc) would be smaller than the number of people convenienced (those
heading east from Midland Rd). If that's true, or rather if, taking
into account the degree of conveniencing and inconveniencing, the net
convenience is positive, then making Judd St one-way would be a Good
Thing. Perhaps it's not, and it seems likely that it's not a big deal
either way, and in either of those cases, it would be a Bad Thing, or
at least a Meh Thing.

No, it wouldn't be a Meh thing. Introducing new legal restrictions which
will make it harder for people to just do what they like should only be done
as a last resort if the arguments for it are compelling.

Pedestrians are presumably more likely to be run over in one-way roads (I
take a few of them out every time I drive past Camden Lock) and even for
aware pedestrians, crossing a one way road is more difficult than crossing a
2-way road of the same width. Judd Street contains the HQ of the RNIB and so
possibly has more blind pedestrians than any other road in Britain.

Anyone who misunderstands the signs on a one-way road is quite likely to
have a head-on collision. Councils in Central London cannot be trusted to
sign one way roads properly. For example, it was possible to turn right from
Guilford St into Herbrand Street and then left into Bernard St (which is
supposed to be one way the other way) without passing any prohibition signs.
The signs weren't removed, they just hadn't been put up. Hopefully they've
fixed it since I told them about it, but since they're a Labour council,
maybe not. (I've spent 3 months or so trying to get an answer from Islington
about the death trap that they or TfL have recently created at Angel, and I
believe someone who doesn't speak a word of English would get a free house
out of them quicker.) The same lethal lack of signage occurs at Hoxton
Square, West Square, Victoria Square etc etc etc. This problem doesn't seem
to happen in the suburbs. It's as if the road network in Zone 1 is so dense
and confusing that even TPTB can't keep track of which roads are one-way and
which roads are two-way.

Anyway, you still haven't given a single reason why traffic shouldn't turn
left from Judd St into Euston Road.
