RJK conveniently ignored by earlier comment. Being hit by bus or lorry at 20mph and you're dead. Are we slowing these vehicles down to 5 mph or is the safety aspect just a smokescreeen?
That makes no sense at all. You couldn't previously exceed 30mph, it's the same thing, except slower.

Car coming out of junction onto 30mph traffic knows he/she can't go over 30mph pulling out, but has 30mph cars going each way.

Car coming out of junction onto 20mph traffic knows he/she can't go over 20mph pulling out, but has 20mph cars going each way. So it's easier. They're going slower. Cautious drivers will love this.

The people who won't love it will be the people who rev the shit out of their cars to zip out of a junction really quickly over 30 will be caught short. But it'll mean those people shunt into the back of queuing traffic less. Another benefit.
