One the sinusoidal humps, or the speed "cushions", you should be OK to keep a steady speed of 20 or thereabouts.

On the flat yes; going uphill or downhill? You can always over-ride and put in 2nd manually?

I do not have a 2nd gear. My 19 year old Ford uses a Vari-Speed system..

It has a 'L' Low gear. which can be used for going up VERY steep hills. Not needed for D.K. Hill.

But then my revs go up from 2,000 to 3,000

James Barber is an idiot, which is why I've never voted for him. Of course there is such a thing as an accident. And in a busy city, accidents are bound to happen. If I drop a glass and break it, that's an accident. Of courseIi could have held it better or gripped it harder. But these things happen. We are not perfect any more than we are totally in control of everything at all times.

Your mileage may vary as they say...my 16 year old Ford will sit happily on the level in 2nd at 20mph, but at 30 it's at the high end of 3rd.

Ahhh

But the system you use to pick up your glass needs to be reviewed

and perhaps quality control of the glass.

There's heaps of room for some management consultancy here.

Thanks Blah Blah for constructive comment!

Sweden has a strategy of going for zero crashes called Vision Zero. Part of achieving that is investigating crashes in a similar style to air crashes - what were the root causes and then they seek to eliminate them. They have seen huge reduction in crashes and the severity of crashes.

Another strand is proper Police enforcement of drink driving, etc.

The naming of crashes accidents has meant decades and decades of just accepting that they happen with little changing. It implies fate. It implies acceptance of people being injured and killed when relatively simple changes to our roads and behaviour could avoid them.

Sorry James - was joking in my post.

But I agree with the Air Crash analogy - as a fan of Air Crash Investigation.

It opens your eyes into how crashes happen.

Thanks JohnL,

You might be interested in a book I have called "Normal Accidents". The idea is perfectly nortmal asctivities that when brought together go horribly wrong. Happy to lend it to you if interested. PM me. I used to help design new systems and systems upgrades and then Kaizan/Lean Production. Lots of crossover of thinking.

[mako]

Not sure you can say decades and decades of nothing happening mr barber, when there is clearly a long term trend showing a decline in crashes.

[Blah Blah]

Here's a constructive comment for you James. As mako above points out, to say that nothing has happend for decades to reduce accidents (in any context you care to choose) is just plain nonsense. Road accidents have been falling for decades, as have the deaths from house fires, as have the deaths from a multitude of sectors because of the work done to reduce them. Show some perspective at least.
