Re: Driving law proposals could see motorway speed limits raised

Yes - if each year you spend about 335 hours driving 23,450
miles at a steady 70mph (in addition to all the other hours
driving further at lower speeds) then your saving if you could
do that 23,450 miles at 100mph instead would just tip over 100
hours.
Once you're over 100 hours you can legitimately say you are "in
the hundreds", but there is a argument that a common
interpretation of "hundreds" means at least an integer multiple
of hundreds, not anything over 100, so a threshold of 200 hours,
i.e. 667 hours driving 46,690 miles at a steady 70mph vs 466.9
hours at a steady 100.
But however you slice it, you might like to try installing a GPS
journey tracker on your phone, and gather actual data on how
much of your journeys you spend at an unimpeded 70mph, and then
factor in an honest appraisal of whether you could really have
covered the same ground at an unimpeded 100mph, given the
realities of other traffic, the weather, the fact that it's
dark, etc.
You might be surprised.
Also, remember that the saving in time will cost you. In theory
power required goes up with the cube of speed. 100/70 = 1.43.
1.43³ = 2.92, so it takes nearly 3 times as much power to travel
at 100 compared to 70. Assuming constant efficiency, fuel
consumption is proportional to power output so you'd be using
2.92 x more fuel to go 1.43 x faster, i.e. 2.92/1.43 = 2.04
times less efficient, meaning your mpg will drop to 1/2.04, so
basically 50% of its figure at 70mph.
Your 100 hours saving will cost you twice as much in fuel over
those 23,450 miles.
Your car may well be able to give you pretty accurate
consumption figures at a steady 70, especially as it would be
measuring over a period of hour(s). If so you should be able to
estimate the cost of doing 100 instead of 70, and see if it is
still as attractive.

There's already a law against that. Maybe it should be subject
to civil enforcement, with TFL given the relevant powers to
enforce it on the M25? It would certainly help plug the recent
budget hole from the 900 appeals they lost.

I'm fine with that (also considering that a higher limit doesn't
mean one has to drive faster, it's just an option). You also
have to factor in that driving at a more sensible speed is more
enjoyable, and I'd rather be at my destination sooner rather
than later given that I'm not getting any younger.
Frankly if it were up to me the motorways would have no limit at
all, in Germany I found 110 / 115 mph brought a fair balance
between making progress and fuel stops.

Without trying to re-litigate old cases, all I can do is to
relate my experience.
I described people who hate Sadiq Kahn because of the colour of
his skin and/or his religion as “knuckle-draggers” – removed.
A while ago I suggested (that was all) that we should be mindful
that John Lyon’s campaign against Bristol’s CAZ penalties might
not be entirely motivated by a purist desire for scrupulously
correct legalities, and that given his track record of opposing
other traffic control measures he might be one of those people
who subscribes to the “war on the motorist” belief, and is
simply opposed to anything which stops him driving when, where,
how, and in what, he likes.
Removed, and a complaint made against me.

I've spent more hours than I wish I had on the M25. Don't
think I ever once saw anybody driving so slowly in any
middle/outer lanes that a convincing case could be made that
they were impeding the safe forward progress of other vehicles,
or driving without reasonable consideration for other road
users.

In Germany there are 75% more fatal accidents on unrestricted
sections than on ones with a speed limit.

I'd not looked at before seeing it cited here as a news source.
After looking at the site I thought maybe it was just posted as
a joke.
