If you actually realised what goes into crash investigation you would know this.
Here's my quals;
- crash investigations officer
- senior police crash investigation mechanic
- senior police driver trainer
- breath analysis operator
So I actually investigated crashes and was guided by experienced investigators to develop my skills. I disassembled crashed vehicles and reassembled them to work out if they were a factor. I gave evidence before magistrates and coroners court. I was present when magistrates made their decisions. I have done the training in the effects of alcohol and the dynamics of vehicles at speed.
This is why I have called you on this. I know what I am talking about and have the experience to back it up. Others here likewise.
Your scenario demonstrates you don't. In that scenario the contributing factors are;
1. Decreased reaction time, vision, vehicle control and perception due to the influence of alcohol
2. Increase in stopping distance due to excess speed from 160 metres to 230 metres based on a dry road and delayed reaction factor of 4.
Both speed and alcohol are factors. The extent to which the driver was ACTUALLY impaired is fluid. A big drinker will function better than a small drinker though both will be impaired. The vehicle dynamics due to the speed are not.
Seriously, in all the years I was involved in road safety I never ever heard ANYONE involved suggest anything within a bulls roar of your 1% speed statement.
Your 1% speed related statement is wrong and anyone who has spent time researching road safety would know that.
Here is the reality. If you are doing 60 in a 60 zone your stopping distance is 50m. If you are going 10 over that at 70 the stopping distance is 62m. If the collision is frontal then that extended stopping distance will, in most circumstances, be a causational factor. 12m is 3 car lengths.
I am very passionate about garbage being sprouted about traffic enforcement measures as it reinforces and justifies poor behaviour that results in lives being destroyed.
Speed is NOT the only reason for serious crashes but is highly representative.
