Pragmatic approach to speed
"Crap drivers cause the accidents - not "speeding""
In France, the speed limit in towns and villages is 50 km/h. There are no speed limit signs usually; this is the default limit written into law.
I agree to some extent that bad driving is as much to blame as speed per se.
I would add two qualifications.
1. In built up areas, where pedestrians are expected to share the road with cars, 30 mph is quite fast enough, full stop.
2. On the open road, if it were to me I would say that any speed is okay on condition that you can come to a complete standstill within the distance you can see to be clear.
Come to that, you should never be unable to stop within the stretch of road that you can see to be clear.
I have to say, though, in some of the posts above I see the impatience and fury mirrored in the faces I see in the mirror when I'm being tail-gated for having the impertinence and sheer effrontery to decide that 55 mph is quite fast enough. Yes, the limit is just that: a limit. It is not a target. Sometimes, depending on the type of road and weather conditions, it is prudent to ease off the accelerator a bit.
If someone gets on my tail, this essentially increases my stopping distance. Why? If I have to do an emergency stop and someone's kissing my bumper, the chances are the cretin'll plough straight into the back of me. So I have to ensure that, if the car in front does an emergency stop, I can also stop safely without being rear-ended. Result? I increase the distance between me and the car in front and reduce my speed.
Tail-gating is just soooooo counter-productive.
Guys: Get a little patience.
