So we need to educate people not to walk out in front of cars without looking, because it doesn't matter if you are going 30mph or 33mph, if someone steps out then they are going to be hit. The stopping distance at 3mph is almost immediate, try it.

malc, that might be true, but the difference of been hit at 30 to 40 say, is they keep their life!
even 3 mph makes a difference.

I think if you look at accidental deaths caused by cars you will find that the majority of them are in built up areas with speed limits of 30 -40 miles an hour. where the driver was only going a few miles over the speed limit.

3mph makes no difference if someone walks in front of a car without looking . A car can kill someone at 20 mph.

Malc, a vehicle travelling at 32mph will take longer to stop, the vehicle will still be travelling at 11mph at the point where a vehicle travelling at 30mph would have stopped. And as you pointed out being hit at that speed is going to do damage.

Rubbish.  We are not driving Austin 1100's anymore. Basically it's like driving at 2mph and stopping sharply. How does that turn into 11mph?

A slight increase in thinking distance but then that depends on the driver. Someone driving at 20 mph and tuning in their radio is far more dangerous than someone slightly over the speed limit.

It takes an extra 13ft to stop travelling at 33mph as opposed to 30mph.
 
So more like they will still be travelling at 8mph when the would have stopped, if driving at 30mph.
 
Those caculations are done from the highway code books on stopping distances.

Yes, the highway code book written around 1962.

never mind the stored energy in an object travelling  for an extra 13 feet,
 
thats the energy when in collision with a human being does  the damage....
 
sorry malc but you are very very wrong on this one...got nothing to do with austin 1100s its all to do with weight, velocity and  the stored energy which does the damage....
 
modern cars are designed to crumple more and absorb more energy in a collision but  you are still being hit by a large lump of metal plastic and glass-  there will still be enegry  as part of that collision, it cant all dissapear.....it just means less energy is directed into the pedestrian...
 
 
need a stella and i need one now !
