Speeding ....again

It was the only vehicle/wheel/tyre size combination that my chains would fit. I had bought them for the Octavia and never used them but they were really expensive ones. I must admit I have only used the chains once since I got a 4x4 (Yeti) with the Sno-Tracs. and that was up in the mountains on a stretch of ice where even the winter tyres had no traction. Normally the Winter tyres are like driving on normal roads when everyone esle is slippin' and a slidin'

 

True.. even a 700 mile round trip at 60 average compared to 70 average adds at least an hours driving time to an already long journey as well as additional break given 60mph for hours on end leads to drowsiness and loss of concentration.

 

Some rubbish talked on here. You are not much of a driver if you can't judge speeds by periodically glancing at your speedo. If you are that rubbish fit and/or use Cruise Control.

 

Max driving time with out a break is a recommended 2 hours. 70 mph for hours on end also leads to tiredness as does 30mph. It's the driving what tires not the speed.

Yes the obsession with computer reaction time over humans is misleading. AI is reactive and does NOT anticipate. Experienced good drivers don't rely on reaction speeds, instead driving defensively and anticipating other road users actions and movement.
Here is just one example of the human brain's superiority over machine... Driving to work on a cold frosty morning on a country lane the car in front hits black ice and skids off road . The driver in a following car sees this and reacts BEFORE hitting the same patch of black ice. Whilst the AI MAY (or may not) be able to control a skidding car better than a human it is merely reacting to an event than need not have happened. Tell me how an algorithm can be programmed to react in that situation. AI may be coming on in leaps and bounds but it is a long long way off being able to replicate the human brain (certainly not within current the timeframe being talked about. Driving is a highly complex multi tasking activity requiring multi sensory input. Much of the processing (where to/the order in which you look and the subsequent processing assessment of the hazard) is subconscious in an experienced driver making it appear simpler than it is.

I used to assess people who were physically and/or intellectually impaired, for their suitability to learn to drive and came to realize how reaction times become less important than anticipating other's actions. Until AI can 'learn' independently and not rely on programming at the level of the human brain then it will only work if automated cars are segregated from both human driven cars AND pedestrians.

 

To <1 mph either side of the speed limit?? Remember we are talking (at 70mph) less than 1.5% error margin 100% of the time. Even cruise control isn't that accurate in hilly areas). I am afraid it is you that is talking rubbish.

 

Err isn't that what I said?? Increased actual driving time on a long journey means more breaks required increasing the overall journey time still further.
Strangely, driving faster ((within the speed limit) improves concentration levels. 130kmh on Autostrada or faster on certain derestricted sections of Autobahn does 'focus the mind' and improves concentration. IMO I find pootling along on said 2 lane Autobahns is bloody dangerous when the speed differential can be > 60mph (if you are doing 65 and BMWs and Audis are doing 130) a bit like pulling out from a side road when a very distant car is approaching at 65mph. What was a dot in your mirrors can quickly become a BMW with flashing headlights up your rear end. It is actually more relaxing and safer to drive a bit faster and reduce that speed differential so you are not constantly becoming stuck behind slow moving lorries etc. .

 

My bigger concern with smart motorways is the danger. A couple of years ago I was driving north on the M1 early in the morning in winter. Must've been 6amish so very dark. I got to around Watford and my battery and alternator both went at the same time. Everything went dead, lights, indicators, everything. Thankfully it was pre smart motorway, but it was hazardous enough trying to get over to the hard shoulder without any power or lighting at all in the pitch black.

 

Let's say we're on a motorway doing 70mph. Ordinarily I will glance down occasionally/subconsciously just like checking mirrors etc. I know that if I happen to stray a mile or two over 70mph there is no harm done, ease my foot off the pedal slightly and job done. When I know that straying 1mph over the limit will put points on my licence and cost me a big fine then trust me I'm staring almost constantly at the Speedo to make sure I don't drift even slightly above 70.000000mph.

The speed limit during roadworks on the M1 was 50mph and I spent more time making sure I didn't accidentally stray over 50 than I did watching the road.

 

Cruise control isn't 100% reliable

 

He does so a lot. Barnsley Brian the blade

 

So he's right then. A 700mile round journey at 70mph will take you 10 hours necessitating 4 breaks. 60moh will take you an extra 1 hour 40 and require an extra 15 minute break as well taking the total additional time to 1:55

 

Well mine has never let me down. If you can't stick to the speed limits pack in driving. Excuses, bloody excuses.

 

How do you know that it is 100% accurate?

 

Anyone that says they have never broken the speed limit by 1mph (either on purpose or not ) has never looked at their speedo, has never driven or is a liar.

 

I vote for option number 3

 

They had a dicussion on it yesterday on the radio and a former road safety guy from Scotland rang up, he basically said the bloke was talking b*llocks wanting no leeway as there were so many variables that affect the accuracy of speedos

 

How ironic a statement is that!
I drive all day everyday do my level best to stick to the speed limits as my job depends on it but anybody who says they have never drifted an odd mile an hour over of the speed limit is talking total balls.
Also if they want to cut down on speeding the want to sort the woefully inadequate signage out!
