Speed awareness course feedback
Discussion
A short while back I was caught at 82 on the a303. My first blemish in nearly 30 years of getting away with it.
Annoying as it was, it was a fair cop.
The SAC date came, dreading 4 hours of being told I was a menace to society I arrived with my preconceptions.
Not a habitual speeder my indiscretions were limited to wide open NSLs.
I didn’t come away thinking such activities as 82 on an open empty dry dual carriageway was a major danger and yet since, I’ve benefited massively from keeping to the limits.
Using the electric limiter has proven hugely rewarding, no stress and it only makes a difference to journey times if doing 200 plus miles in open clear roads.
It’s really helped me arrive less stressed, sure I can still get my fun, driving rewarding roads but keeping as close to the safe limit is far more rewarding.
Have you been on a sac and has your driving changed?

Chris I’m 43. Like you I stuck to all other limits and even on the motorway commute I’d stay around 60 as you got there no quicker but at most I’d typically go to 77 on the clock.
Day I got caught I obviously was doing more but I got caught.
Missus laughs. She never obeys any limit and unlikely to get zapped due to the roads she drives. Humph.

Whilst I've never been on a SAC, the most interesting fact seems to be that a fairly trivial increase in speed (30 -> 35, say) results in a disproportionate increase in kinetic energy of the vehicle, and a disproportionate increase in impact speed if an accident occurs.
Both make sense mathematically, but aren't immediately intuitive.
The video showed an increase of 1mph became an extra 8mph at the same stopping point which seems a bit bsBoth make sense mathematically, but aren't immediately intuitive.

I do the same and speed every day.
If you don't know better then I pity you, I know my capabilities, I know the weather conditions, I know the traffic, I know what car / van / truck I'm driving, I know what load I'm carrying... so obviously I can make a better judgement on my speed than some random number on a stick.
Exactly what scientific approach do you think was used to set the limits and how often are they reviewed ? It's the same limit at 6am on a sunny summer morning as in the snow, in the dark, at rush hour !
I can tell you in the last 25 years I've had no accidents.
Been let off with a warning approx 10 times
Had one SAC
Had 4 sets of 3 points and fines
Have held a clean license for at least the last 10 years
Now, what was your point ?
Either you’re trolling or you genuinely believe this. You have an extra duty of care she driving loads as each load is different you would hope professional drivers would take a greater duty of care. This isn’t Shakespeare raceway If you don't know better then I pity you, I know my capabilities, I know the weather conditions, I know the traffic, I know what car / van / truck I'm driving, I know what load I'm carrying... so obviously I can make a better judgement on my speed than some random number on a stick.

You haven’t included friction to your calculations
You are working it out that both the cortina and the 911 have the same coefficients, brakes nor are you taking into consideration weight distribution, spring rates etc.
No, I'm saying that the Cortina at 30 mph has the same brakes, weight distribution and springs as the self same Cortina at 35 mph, and the 911 at 30 has the same brakes, weight distribution and springs as the self same 911 at 35 mph. You are working it out that both the cortina and the 911 have the same coefficients, brakes nor are you taking into consideration weight distribution, spring rates etc.
We are talking about the same incident. A Cortina braking from 30mph at point A comes to a halt at point B. Had it been doing 35mph at point A, it would be doing 18mph at point B. Same for a 911 (although point B will be closer to point A for the 911.)
People can argue this until the cows come home, but they are wrong, and Sir Isaac Newton was right. The laws of physics don't give two hoots if a human thinks they don't sound right.
