I’m sure that many readers will remember the days when petrol stations had attendants that put the petrol into the tank for you – before the days when “self service” became the modern way of filling up.

Well, perhaps we are going to return to that kind of service. I’ve been fascinated today by a video of a petrol station in the Netherlands, that uses a robot arm to fill up the cars.

The robot knows from the type of car how to open the petrol cap, and presumably whether or not to put diesel in. I wonder how it copes with bio-ethanol?

It looked rather slow at the moment, so I guess the queues at the petrol station near here would just get longer. I also didn’t see anywhere to pay for the petrol – does the robot arm swipe your credit card as well?

As fascinating as it is, I’m still not too sure what to make of it all. It may be nice not to have to get out of your car, but it doesn’t help the unemployment figures!

Tonight I read about London’s new “low emission” zone on the BBC News website.

Germany has been talking about such schemes for a while now, indeed they started issuing the discs last year and I have a green one in my bio-ethanol car. But until now it has been up to the individual towns and cities to decide to implement the scheme. At the start of this year, some of them did – causing discussion amongst the population of the affected cities.

I myself will be travelling to one of these soon (Cologne), so I shall see for myself it it has had an impact.

But back to London – the scheme seems to be more controlled than the German ones, but covers less vehicles.

For a start, cars are exempt to the London scheme – they are not in Germany. In fact, even foreign cars have to get their discs before entering the zones.

On the other hand, the London scheme is being policed by CCTV cameras – something that German cities do not have in such numbers, and even those that do have them cannot, as far as I know, use them to this particular cause.

Critics of the scheme will no doubt sight the cost of upgrading vehicles, something that has been discussed in Germany as well.  Whilst this is definitely a valid point, and Germany has made a number of exceptions for residents to avoid the issue, it’s got to be a good way to start reducing the emissions on our roads, hasn’t it?
