ST/Motorways for learners
That should give some nice trips south for Highlanders and Islanders!!
Motorway access should be by a "motorway rating", as well as night driving by a "night rating", only available after a test or at least a check ride. Drivers living where there are no motorways needn't take the rating.

Just drove up the A1, 2-lane and apart from two trucks at 56 with a couple of cars following, the two streams were travelling between 69 and 71. Scarey in a way

Go by Elon Tube? Drive on, traverse LA at 160mph, and drive off. I think that sounds like a good idea . . . except perhaps for plate tectonics, and Sod's law.

Two weeks ago, I was tailgated through the length of my large village.When I pulled into my pub car park, the vehicle followed and parked opposite. As the young female driver got out and walked past, I raised the boot lid and invited her to inspect the contents. When she asked why, I said - smilingly - that she'd been trying to get into it for the past mile. In return, she also smiled and moved on.

This may have been covered previously on PPRuNe, so apologies if it has.

Recently, we were driving on an active 'smart motorway', (The M62), with the speed restrictions varying in both space and time, and naturally started to discuss the system.
One thing that came up was the change in speed limit as you approach an individual gantry/camera installation.
If, for example, you are 2 are 3 vehicle-lengths from the gantry, and it changes from 60 to 50, or 50 down to 40, how long before the camera mounted on the other side starts to 'flash' vehicles that are still travelling above the new lower speed?
Does the 'gotcha' system have any time-delay to accommodate gradual deceleration, or is it instantaneous? The amount of braking I have seen when the limits change would imply that many believe it is instantaneous.
Also, I think there is a case, (or not, if you're an accountant), for the new limits to 'flash' for a short time as they change. The current system does not really act as an 'attention-getter', and I find there is need to monitor the gantry, at the expense of watching the vehicles around me. This is easier with 2 pairs of eyes in the front, but the mental workload on these 'managed' sections certainly increases.

As an engineer, I would build in a reasonable grace period.

Then, as a politician, I would refrain from telling people exactly how long it was, as they'd think think they could always ignore the signs for that long.

I found this, apparently from the UK Highways Agency. I have yet to confirm this.

"When a mandatory speed limit changes on the overhead AMI signal, there is an automatic one minute delay before enforcement can begin against the newly displayed limit. The flash units can still activate during this period, even though the new limit would not be enforced. In this situation, drivers are not expected to brake sharply, but rather to reduce their speed so that they are within the speed limit as soon as it is safe to do so."

Edit: found this Highways Agency link from which the above quotation was taken. Also noticed that if the sign above your lane isn't showing a limit, but the other lanes are, the limit still applies to all lanes.

We have a local Toll Road charged via overhead cameras, and I find that occasionally I can get a free passage if I change lanes at the correct point - never actually decided - just before passing under the gantry ! Such fun.

There aren't any "speed" cameras that I know of here in Delaware, but there are a bunch of stoplight cameras that will snap your picture if you go through on the yellow.

I guess at that point it's up to some gubbin (new word I saw in another thread, don't know what it means but it sounds bad) who sits around analyzing pictures and putting his gubbin "X" on the ones he thinks ran the light.

In some very low speed zones, we have these l@ser speed signs that display your speed as you approach, and throw an absolute fit if you're 2 miles over -- "27! 27!" -- a flashing display that makes you feel bad enough to get distracted.

The thing that really grinds my gears are the faulty coin-catchers at unstaffed toll booths.

You throw your $0.50 in the bucket, and the sign still says "toll due" and you sit there and wait for half a minute, throw another four bits in the bucket, and it still says "toll due," so you drive away.

Two weeks later, you get the fine, delivered in the mail, based on your car's license plate.

If they can put a f*cking camera up that can do that, why can't they put in a f*cking automated change counter that works?

Cheers!
Ray

I like your ingenuity but for the avoidance of confusion and doubt 'gubbins' is a UK (originally slang I think) word meaning the miscellaneous parts of something rather than a person.

There's one of those in Cambridge set to 20mph on a road where there's nothing stopping you going as fast as you like on your bike. I've got it up to 24, but could probably get it higher if I tried really hard.

"A few comments about American traffic & roads.

1. Everyone exceeds the speed limit (TRUE, and by quite a lot)
2. While the quality of the roads is not good, the design isn't bad at all. I especially like the centre turning lanes in towns. (TRUE, I agree)
I like the 'right turn on red after stopping' rule. (Absolutely the best way to keeping traffic moving)
3. I don't like the way speed limits change so often. (Often dependent on local town, county)
I do like the generally higher (than Australia) limits, except in CA. (Looks like you only saw the Vegas-LA corridor, and the LA area. Elsewhere, in particular N of LA on I-5, or Hwy.101 the speeds are quite high, you just have to be aware of the habits of the "fuzz").

I have lived in the US for almost 50 years, in CA for over 40, I have driven in all 50 states and into Canada and Mexico, many times.

Some councils are all-a-glowing with a shared bicycle scheme. This is what is happening in Beijing and the rest of China where they have had this facility for a few years.

When I was working in Japan many moons ago it was a common sight at suburban rail staions around Tokyo to see masses of bikes "parked" (jumbled might be a better word) outside.
Frequently the "spares" would be rounded up en-masse and dragged off.
My friend told me that he'd bought many bikes over the years and would eventually just choose one to take home at night, as his would be lost in the morass.

Lost in the mass, in Bruges there is also a massive bike heap. I wonder if that is find-yours or grab-a-wreck?

Many people in Cambridge are not best pleased with the dumping of Chinese bikes around the place. Including me - I didn't get several hundred new bike racks put into the city centre in order to provide free storage of their stock for a commercial operation.

GTW, simple solution. Chain their bikes with YOUR chains.

To help rotten ray.
It's the gubbins inside the coin sorter that aren't working.
