"As far as the speed limits are concerned", driving a stolen car whilst
pissed and banned from driving is legal.

How? Given that they have little or no effect on traffic speeds.

Studies in the U.S. showed that speed limit reductions have little or no
effect on speeds, other than to increase them for many of the drivers
that would otherwise be driving below the new limit.

Then how did they pass their driving test? Surely that's an argument for
increasing the level of skill of drivers, not relying on measures to
protect everybody from one relatively minor result of that incompetence?

Just like they ignore speed limits, y'mean? And yet fatalities from speed
above the limit are a small minority of all deaths...

You've given reasons which you think are "perfectly good" - yet every
single one turns out to be lame or false.

No, you just keep saying "because they're for safety" instead. Despite
they fact that even you admit they are at best "approximate".

Yes, but they weren't the subject of this thread either - the efficacy
of speed limits was though.

Better value though than something that doesn't work at all.

Look at the experiences from the introduction of 20 mph limit zones in
vast areas of Portsmouth and 20 mph limit zones in vast areas of Hull...

The ones in Portsmouth didn't make any difference at all to traffic
speeds or to accident levels. In Hull traffic calming was first
installed to slow traffic down, then when the speeds had dropped below
20 mph (and the accident numbers had dropped correspondingly), 20 mph
limits were added (and subsequently given the credit for achieving the
results).

The speed limits brought exactly the same benefit to both places: none
at all.

That's why "20 mph zones" cannot be introduced now until the traffic
speeds have been reduced to less than 20 mph by "traffic calming".

The authorities continue to treat the general public as idiots, and fail
to admit the reality that limits _do_ _not_ _work_.
