Traffic Engineers/Speed Limits etc

[David's8]

I get the impression that road/traffic engineers really HATE motorists. Not only do they devise and build poor roundabout that (deliberately?) un-sight you as you approach causing people to either pull out not realising that the car they saw a few milliseconds ago looking as if it was going straight on has now decided to come around or else they break when not required causing accidents behind them from others who can see that the roundabout is clear. (There are several like that in my area).
I KNOW that they'll say "well you should come to a halt before proceeding and its all a lot safer" buts its bo##ocks. The greater risk comes from not having a clear view of the roundabout. Fact.

And now the to##ers are looking to implement 50 or 60 mph limits wherever they can for whatever excuse. The bridge across the Clyde at Erskine will have a 50mph limit when they have finished the interminable work on replacing the barriers protecting the supporting cables/tower structures. This is for all vehicles no matter what the difference in mass between them. So the 30tonne tipper truck will be the same as a Micra? wheres the logic in that? The barriers will be designed to deal with a certain impact speed and vehicle weight. why not use that info to inform the speed limits such that it is based on real risk arguments!Keep the trucks to 30mph (or whatever), limit them to the one lane and let the cars go at 60 or 70mph.

And another thing, the M1 will have a stretch of 35 miles or so with a limit of 60mph. For environmental reasons.
The A9 - a notoriously dangerous road - will have a 50mph limit ALL ALONG ITS LENGTH as the government wont put money into dualling it all in a reasonable timescale. That'll make it MUCH safer, i dont think - all the caravans, trucks and cars bumbling along in an everlasting queue. They have effectively banned overtaking. When it gets to the dual carriage sections every body including the trucks will be attempting to overtake everybody else. Once again - a load of bo##ocks.
