It’s busy on my trading estate. The worldwide demand for Ruppert products and services worldwide means that there are three couriers a day popping by to pick up parcels of best-selling books, cuddly toys and car parts.

However, after observing some inaccurate driving by the courier vans I was forced, for the sake of the grass in the staff recreation area, to break out the cones.

It has improved driving skills slightly. The rock-filled micro cones have been crunched twice so far. And the point of all this is, just what group of professional driving society are the worst?

Without naming courier companies, the one that calls first employs private drivers and she couldn’t be more careful. After all it is her Ford Galaxy. So no screeching to halt on the handbrake or cutting any corners at all.

The next courier can variously turn up in a variety of vehicles, especially after the last regular one quit. So far it’s been a removals van and a fishing tackle logo’d Transit.

Finally the best-known courier company in a Mercedes-Benz Sprinter almost catches air when entering the premises and he’s the one who has flattened the cones. Parking the Land Rover near the corner has slowed him down no end.

Talking to a HGV licence-holding friend who is restoring an 1980s ERF, he believes that the worst professional drivers are couriers and container lorry drivers.

Anyone agree or disagree?
