apply (factoring for conditions).

If your gonna say ‘the brake lights may not be working’ then that’s why we need real trafpol, not speed cameras.
We also need more vigilent drivers who bother to check their brake lights, and other lights on a regular basis. I know some will "just go" on you, but on a personal basis I check mine weekly, how often do we all see cares with either no brake lights, some stuck on, and the one headlight stuck on full beam.

Lots of questions there, too many to answer individually.

The 295m isn't something that I came up with, it's quoted from TD 9/93, which is the standard for the design of highway alignments. It's used for the design of every major road. It's based upon the experience of many hundreds of engineers and scientists and empirical data gathered over several decades. So I think that it's quite a useful source.

To clarify my point; safety is dependent on a large number of factors, one of which is speed. Whilst reducing speed has a number of effects, both positive and negative, it is the finding of my training and experience that the net result is beneficial for safety.


Interesting info I'd like to find out more about the highways design side, eg the white line hazard layout "system" etc etc. Is there a good online source of info.

I certainly agree that an increase in speed requires a far more alert/trained driver, though I'm happpy to drive at what would be deemed illegal speeds I'll maintain an extended stopping distance/gap additional lane on motorways. Yet many many drivers seem to think it's perfectly safe to use said gap for their own use. at 100-120mph I'd be looking at leaving at least a 3-4 second gap infront & an additional lane if possible.
