Driving faster can help a driver be more alert yes, I totally agree and may even utilize this tactic on occasion.. But it can also be more dangerous to the person driving slow so a happy medium has to be met..which is why we have speed limits...It would be nice to be able to trust all people consider their surroundings and drive accordingly but unfortunately too many people just cant think for themselves and others at the same time, many also don't fully understand the risks...these people need structure which is why we have road rules...
I also feel that the excessive policing and scare tactics we have is possibly in effect making many people worse drivers, because they are now way to nervous to actually drive on the road they are becoming a hinderance to those that can confidently drive well..
I'm out there all day everyday, every second person is speeding or on the phone at some stage and those that aren't are driving too slow, not giving way etc etc..that said though I dont really see many accidents caused by it..I do see alot of pissed off people, but you get that when common courtesy (just like common sense) is that common..
So I do wonder if there is as many do-gooders as we all think sometimes...maybe the trouble is just to many do-gooders doing surveys and spruking their shitty opinions.. Often with little real world experience.
Accidents will always happen and wrapping everybody in cotton wool isn't going to stop that...With the amount of cars out there on our roads everyday zooming around, Im surprised there isn't a whole lot more accidents...
