If you follow the usual rule, that you must always be able to stop in half the distance you can see to be clear, then if you can't see so far you can't go so fast, therefore you have to slow down. Basically just physics.
Indeed, if you are going that fast. However I see a lot doing it at 30mph, when they should surely still be able to see. Wonder if older eyes not as able to cope with contrast changes or something like that.

(While we are drifting, just for a sec.)


Running Xenons in one car, but not sure of their legality in the UK.


Fitted a large single LED bulb in each headlight of the wife's car last week and these are also seriously bright.

GTW, but then I am more used to driving one on one in Lincolnshire. Certainly with a stream of opposing traffic it ux different.

If the road is clear a quarter mile or more ahead in my headlights, and I leave my lights on until the other car appears around the bend, where is the unlit cyclist or parked car coming from?

Digressing, one dark night on a poorly lit two-lane one way road, as I camevround a corner, this idiot on an unlit bike hurtled the other way. How he avoided me I have no idea. I was doing less than the limit - 20 - he was extremely lucky.

In 1965 I 'built' my own quartz-halogen bulb adaptors to fit them to my headlamps and auxiliary lamps (H1 to pre-focus).

I also acquired some 75 watt sealed-beam units.

G-CPTN, snap, I also altered the circuit so the control operated on relays to reduce power loss, same on the fogs.

I also drilled the gearbox to fit automatic reversing lights.

Carried the relays over to my SAAB and later added rear fogs and cruise control. Transferred the cruise control to 3 more SAABs.

Makes me shiver now. Now I even have trouble finding the engine and as for wiring, totally invisible and all Canbus sensitive.

Can't remember the year (!!!), but I do remember everyone pressing on at a good lick. Should I have said "before speed cameras?"

If you have to brake every time a car appears in the opposite direction you were going too fast in the first place!

Drivers with poor night vision often give themselves away. They drive well below the national speed limit on the open road, then irrationally accelerate in a built up area because there is street lighting, not infrequently disobeying the lowered speed limit. Some of these drivers seem to have "their speed" at which they drive, irrespective of the actual speed limit (and the long queue of frustrated drivers following behind them). Elderly men seem to be the worst offenders.

Depends on circumstances, but I thought (maybe mistakenly) we were talking about narrow winding rural B roads, in which case someone could come from a side road or farm gateway or driveway you hadn't seen.

Usually 40mph, and time was you could recognise they because (a) they were driving a Triumph Herald and (b) they were wearing a hat. But there's more diversity these days, so not quite so easy to spot.

These days (a) is a Nissan Micra, or latterly a Honda Jazz. Beware if it has a fish symbol on the back allow 5-10 mph less and will brake to a stop at every roundabout even if no other traffic is approaching.

GTW, in Lincolnshire winding B roads are in the majority. Curiously side roads are rarer as we learn to our cost when the council closes roads. Also we have many fen ditches which reduce farm access and that drive after dark unless they are after ATMs.

ShyTorque, I think you make an excellent point. When they can see better they drive faster.

I admit to being an old driver, by some definitions, but try and drive at the speed limit when safe. Our high street is half a mile long. At 15 mph it takes 2 minutes. At 40 it takes 2 minutes as there are cars parking, double parked, turning, pedestrian crossing etc but trying for 40 they do.

Weekend Drive...

My room mate (an 87 year old man who doesn't drive much) and I took a trip from Dover, Delaware, to Hightstown, New Jersey. (Route, google maps).

Obviously, I drove. He has a 2011 KIA Soul+, a sweet little car. 4,000 lbs, 142 horse, seating at butt level when you open the door, just about as big inside as it is outside. Hums along fine, perfect with cruise control.

Traffic early Saturday was pleasant, without too many of these twelve or fifteen car clusters caused by idiots who sit in the two high lanes going slow, and simply won't pull over unless you PIT them.

Sunday afternoon, we ran across an accident that was either caused by someone falling asleep at the wheel, or a minor altercation with a vehicle that then continued on. The car we saw had gone through a guard rail and embedded itself in a stand of trees. Clothing, et cetera, was scattered around, and we had to dodge to one side or another a couple times ot accommodate emergency vehicles.

One minor fender-bender, someone coming down the highway didn't believe all the other cars were stopped for an accident, and plowed into the ass end of the one next to us. Splat, and more traffic tie-up for the folks behind us.

I observed about 200 drivers who couldn't, or wouldn't, maintain a steady speed, causing the rest of us to have to pass them. Or make room for them for passing. Only to pass them again, as they got on their cell phones or started arguments with other people in the vehicle, or decided to eat something, or just wanked off.

Three people entered my lane, causing me to brake, accelerate, and avoid. Two of them were texting. I could tell that one of them was a Verizon subscriber by the phone and the detail I could see. One was eating fried chicken from Popeye's. Yeah, it was that close. I could see the logo on the box the arsehole had on his dashboard, and watched him pull a drumstick out and then weave into my lane as he got the beautiful, juicy chicken in his mouth.

I observed 17 drivers who were going supra-legal speeds, passing us (we're going 70mph) like we were standing still. I'd guess they were going 90 to 100 mph.

21 drivers cause everyone else to slow down because they didn't know where the f**k they were and just had to slam on their brakes and dart across two or three lanes of traffic.

All in all, it was a good trip.

And that's why my rule is "put those idiots in the rear view mirror where that can't hurt you?" Speed is life.

Scary moment, two lane, doing 70 overtaking beat up 4x4 and equally beatup caravan.

Caravan offside wheel departs and over takes the combined and is ahead of me. Collides with barrier and crosses back over two lanes.

Caravan wheel hub now like Catherine pin wheel. Caravan starts to snake, 4x4 starts too snake. Oscillations increase, caravan topples side of road, 4x4 swings opposite way.

View in rear view mirror quite spectacular and amazing no other vehicle involved.

That was third attempt to kill us that day. We felt quite safe four the rest of the journey.

Here's an interesting site. If only . . .


If only one could have an advanced licence that absolved one from all road traffic laws. It would be so costly to achieve, say like an ATPL, and one would work very, very hard not to lose it.

Like minded people.



Safe Speed Background Page



Mate of mine was going around a dual carriageway bend at around 100mph. There were bushes and trees making a solid wall on his right. To his surprise, a genteel lady on a bicycle came round the bend heading the other way. I've just measured it, she was 1.2 miles from the last place she could have entered the highway.
