How Wireless EV Charging Works

[JohnW2]

Agreed. I believe on speed awareness courses they tell you a lower speed is safer than a higher one, KE proprtionbal to V^2 and all that, but that logic applies all the way down to zero speed, and as you say, in real life there has to be a compromise.

Quite so. There's obviously an analogous way in which one could eliminate all deaths and injuries due to electric shock
... or those due to the use of ladders ... or power tools ... or kitchen knives or .....

Do you know where that 'evidence' can be found, and exactly what it relates to?

I take it you didn't bother to read the document I linked to.

One certainly has to take the behaviour of insurers very seriously, for the reasons you mention. However, I'm pretty surprised since, even if one lives in/near a 20 mph area, I doubt that driving on 20 mph roads constitutes much of a proportion of the driving they do.

You seem to be surprised by much of the evidence relating to 20mph speed limits.

It would be interesting to know the nature of the claims upon which one assumes the behaviour of insurers is based.

You can read as well as I that insurers are seeing reduced numbers of claims and reduced values of the ones they do see.

Ooops! I should have (given it's appearance), but didn't, twig that the text you quoted was actually a link Watch this space!

I am (surprised), at least in terms of the area in which I live. As I wrote, more than once, the 20 mph limits around me have nearly all appeared in places where there were so few significant/serious 'collisions' with 30 mph limits that there really was minimal scope for any change to reduce the number appreciably. Maybe it's different in other parts of the country?

If one is talking about a small village where there have been few, if any,'road traffic collisions' in decades, changing the speed limit sounds rather like a solution to a non-existent problem

You can read as well as I that insurers are seeing reduced numbers of claims and reduced values of the ones they do see.

That one I did realise was a link but I haven't yet had time to look at it (but intend to). When I wrote "It would be interesting to know the nature of the claims..." I should have written "It will be interesting to discover the nature of the claims ..." (assuming, that is,that the linked report tells me!) - so, again, "watch this space"!

Kind Regards, John

I've had an initial quick look. There's an awful lot there, the great majority of which does not relate to the issue I was addressing (the effect if 20mph vs. 30mph speed limits on casualties). I'll need a fair bit of time to try to see the wood through the trees., but time is not something I have a lot of at the moment!

One thing I did notice is that, in a good few of the studies reviewed, figures are given for the effect of reducing speed limit from 30 mph to 20 mph on average traffic speeds, and, in most cases, the effect of the change in limit was to reduce average speed by between 0.5 mph and 2 mph. It's probably a bit optimistic to expect such a small reduction to have much effect on anything!

That newspaper article does not say very much. However, it seems that just one insurance company has decreased premiums as a result of a reduced number and size of claims in the 3 months following a widespread and much-publicised decrease to 20 mph limits in Wales.

I would suggest that they need to wait a good while before drawing any conclusions, and that is perhaps what most insurance companies are doing. In the period immediately following such a widespread, publicised and discussed change, drivers are likely to be thinking more about such things and maybe 'driving more carefully'. However, once they have 'got used to' the new limits, that might cease to be the case, so I think that everyone, including insurance companies, probably need to wait for a yearor three to see if any initial apparent responses to the change actually persist.

However, returning to the general issue, I still stick with what I've said before - that solutions should only be implemented to address problems. If, in a particular area, there are a significant number of road casualties then, sure, try reducing the speed limit (even if it is already 20 mph!). However, in an area where there are virtually no such casualties, then it is hard to see any justification for meddling with speed limits (to have an impact on casualties). However, as I've said, I'm only considering the collisions and casualties. The report you linked to talked about all sorts of other alleged benefits of reducing speed limits, ad am not considering them

Not just statistics - A reduction to 20 locally, as reduced noise, made the village generally a much nicer place to live, and it feels less stressful being out and about. Unfortunately, there is no enforcement, so the ones who ignored the 30, continue to ignore the 20.

Fair enough. As I wrote (and you quoted) ...

.... The report you linked to talked about all sorts of other alleged benefits of reducing speed limits, ad am not considering them

So, yes, there are considerations other than collisions and casualties.

However, in terms of the issue you mention, as I've said before, if one lives close to a busy road or railway (I've done both,m and got both T-shirts ), one rapidly comes to 'be totally unaware' of any noise (it';s only 'visitors' who notice!) - and 30 mph traffic doesn't make that much noise, anyway. Of the many possible arguments for decreasing speed limits, I would personally think this is one of the weaker ones.

The A458 I hear no traffic at either 30 or now 20 MPH, the B4389 yes due to how steep, but the train with a speed limit of 15 MPH which runs alongside the A458 yes we hear the whistle quite often. Before they can move, they must blow the whistle.

Nothing like an ECE, forget ICE.
