Because it works better.

Not really, but it saved copper in the 1950s,

It does do that. But actually makes more efficient use of materials. It
gives more consistent results over the entire circuit which a radial
can't
achieve.


If there is a break in the circuit, all the sockets may still work. The
circuit breaker won't trip. Yet one arm of the ring is taking all the load
that's meant to be divided between the two. Isn't that going to lead to
overheating?


It could do depending on the load of the circuit and the installation
methods.

And of course a break on the earth of a radial circuit could be worse.
