The speed of impact yes. That does not necessarily equate to the free traveling speed.

The speed of impact
SMOOTHER driving, you say...Whilst the sweet spot of the engine in terms of efficiency may make a slight difference this is not significant.
So, the mechanics and physics are quite clear. Smoother driving to a lower limit will always require less energy, less fuel and produce fewer emissions than repeatedly accelerating to a higher limit
keep going - you can lead a troll to truth but you can't make him think.
It's weird. It's almost like they know speed is a factor but would rather squirm and bullshít their way around it. And when they see that deaths and serious injuries has fallen since the introduction of the 20MPH limit, they refuse to believe their own eyes.keep going - you can lead a troll to truth but you can't make him think.![]()
Not to mention people walking across the road staring at their screens, and food delivery bikes weaving in and out of traffic and on pavements, wearing no hi-vis, helmets or lights.Speed does not kill, abysmal driving standards & pathetic attitudes to fellow motorists does.
Or like in my diverse town the local communities send somebody else to sit the practical test for a learner driver. Could be why the local community driving is so bad either that or they do not accept man made laws when it comes to speed and seat belts and the amount of people a car can legally carry or thinking holding a child on their knee is a correct child restraint seat..Speed does not kill, abysmal driving standards & pathetic attitudes to fellow motorists does.
Lower speed at impact causes less damage, obviously, but it doesn't follow from that that a given stretch of road will have a lower overall casualty rate with a lower limit.How many stationary vehicles are responsible for pedestrian deaths, v's those vehicles travelling at speed? The speed of the vehicle in a collision is always a factor, regardless of who is driving.
I'm sure what you say is true, but if it were just a money earner, you'd expect they'd be out there booking drivers. IMO 20 mph zones are decided by people who can't drive and have a grudge against those who can.The 20 limit is not there for safety, or to improve the local amenity - it's there simply as a money earner for local authorities, to gain points, and top up their funding when they need to.
I suggest you stay out of Wales or the Greater London area, boyo, or you could end up losing your license.The 20mph is absolute nonsense, and will remain so, unless it is enforced, and enforcement is quite rare.
meaningless word salad.
Meaningless to somebody who can't (or won't) understand simple logic
Lower speeds = less dead or seriously injured.simple logic
