Hmm .. So lets say the human reaction time is 1.5 seconds.. So that is pretty much average for a normal human (excluding athletes) ..

In that time to hit the brakes (only at 50k's) you have travelled about 27 meters... If you are doing 100k's, you are travelling 61 meters ..

If he/she slams on his brakes, and you are 50cm behind them .. There is no way in hell that you are going to stop .. Mainly because you would have travelled a minimum of 27 meters before you can react .. This is simple maths ..

Please think before you type... There is a reason they tell you to be 3 seconds behind the car in front of you ...

like i said almost all accidents can be avoided

So when some asian lady hits the side of my car as I'm going through an intersection that can be avoided?

YOU can personally avoid all accidents, but it's the other drivers you need to worry about

im sure under 25 your cars limits are a lot higher than your own limit...

and if you havnt had an accident then you have no idea how easy it is too have an accident, im sure, everyone who's had a decent accident would drive a lot safer than anyone who hasnt.

just my personal opinion, not an attack, but its very common, its called confidence... and confident drivers are dangerous drivers

not to attack you, but...

Nah I totally agree with you. Was just putting it both ways.

I'm sure that my car could handle a lot more than I do give it, but I'm very realistic about my ability (or lack of) to push it to it's limits.

Don't worry, I'm definitely not an overconfident driver. I'd be too scared to even dream of getting any level of wheelspin in a RWD, for example.

LMFAO

You're a fool,
enough said

As has been pointed out, mathematically impossible if your travelling at any speed over 1.2km/hr assuming your reaction time is 1.5sec.

ie... @ 1.2km/h you'll travel 50cm in 1.5sec (avergae reaction time)

Lol, less than 50cm...you've got no chance mate. You probably be arseing the car in front before their brake lights even fired! And yes, incandescent globes take time to light/brighten. That's the reason many cars now use LED lights for brakes...they light faster giving an earlier warning to people behins and that matters when travelling at speed.

Lol, stop in time...what if the car in front is running upgraded brakes...

50cm was such a massive exaggeration lol

i am a wanker on the road
i should have split my posts up
when i said that most accident can be avoided
and then also stated the bad driving habits i have


my bad driving habits cause accidents
im not going to deny that

ill try to work out what i believe i could safely stop at
average reaction time is .190 seconds

mine is quite faster than that (i had tests that said my reaction time, i had to get them done after i had a footy accident and damaged my propreceptive nerve? something like that was hospitalised for time, had lots of physio etc so im all good now, dad most likely has them in his filing cabinet i will have a look tomorrow or in the future to see if i can find them to tell people the precise thing)
also in my first year of hockey i got selected for 1st grade to play keeper and then went on to get player of the year
(sorry if that sounds like boasting in a way im just trying to back up my story of having fast reflexes because i know many of you will question it)


travelling at lets say 60km/h which i would say is a high speed to be tail gating someone at

if the car slams on it breaks on an average road it will take it 25m to stop


im going to leave out the variable of how a car slows down faster at the end because i wouldnt be sure how to put that in not great at maths or physics

im going to say my reaction time is around the 0.13 mark, again i am not positive on this

it will take me 2.1m longer to stop

and thats if the car completely slams on its brakes to slow down because of a danger in the road ahead or something similar



if a person came flying through an intersection and lets say they come into sight 2-3 seconds before hand
the length of your car is roughly 4 metres
it can go 0-100 in 6.9 seconds
so you could speed up to get out of the way if you judged it correctly


edit: also just to add to my car limits > greater than my own
i realise that
and also about the not to attack you part, id rather you tell me im a f**king idiot and get yell at me then to try to be not offensive about
i love a good discussion that makes me think in different ways, yet another reason why i post this stuff

Brad, you're a f**king idiot lol!

I just hope you don't end up learning how wrong you are the hard way...

lol i expect i probably will, because with <0 experience my theories seem flawless

Tail gaters are the absolute worst for motorbike riders. The amount of times Ive been doing under the limit minding my own business to have some nuff nuff fly to my rear tyre and then without indicating change lanes and blow past me is utterly dumbfounding. I find it funny how they get stuck at the next lights and ill just filter through the traffic and wave to them. Priceless face. In all honesty though tail gating is very dangerous and people who do should be shot. The c**t who rear ended me is one example.

Sure we all speed occassionally (running late, gotta pee etc..) but the speed limit (no matter how much I believe that some roads should have higher speed limits) is just that. A "limit." And these were devised to take into consideration heavy traffic flow, which mainly happens twice a day. So for example when it is night time when theres no traffic, the speed limit hasnt changed and 'people' shouldnt drive any faster etc..

In regards to the reaction time thing, most people perform at the fastest reaction time under pressure. When adrenaline is kicking in. The situations you spoke about are in sports, hand eye coordination-->goal keeper etc. Frankly when you are driving you should be at emotional ease, not highly strung and definately not in the same state of mind as when a puck is flying at you. You're reaction time wont be as fast when you are trying to slam on the brakes at a metre behind someone as when you are trying to stop a puck.

There are so many other variables to avoiding rear ending if you are tail gating to consider. It is not just your reaction time. What about the road surface (different compositions of asphalt and concrete will have different coefficients of friction, and yes although measured in decimal points, these count), weather conditions (glare causing momentary blindness etc), other "like minded" drivers, errors in mathematical calculations, the list is endless. If anyone can say that they can safely drive like an idiot is the dumbest thing I have heard in a while.

Now all this begs the question why bother doing such dumb things when the end result is a few minutes? Having a driver's licence is a privelage, not a right.

Yes I feel strongly about it. It is this exact beaviour which has endangered my life whenever Im on the bike. People should wisen the f**k up. I used to think like you Brad, but experience has taught me its just worth driving like a cock.

Just my 2c

motorbikes are a deathtrap (no offence) hence i always avoid going near them on the road, i have never tailgated nor would i ever tailgate a motorbike simply because of the insane dangers of it. what could be a simply rear ending on car can mean a life on a bike.

when i am driving recklessly and aggressively i guarantee you i am highly strung for a reason otherwise i would be relaxing when i am driving. most times when i drive it is from point a to point b in a hurry and with the current lifestyle i am living it i often dont find the time to enjoy driving

the coefficient of friction is the same for both drivers there for it cancels out of the equation, like most other variables

speed limits are designed so that the worst driver in the worst car can go it comfortably, but i agree with you the limit is a limit


also another thing to add in just cause im curious about it
whats everyones views on if the rta made forceful tests for driving every 15 years or so to make sure you keep up to date with road rules and are still skilled enough to drive. because i personally think many old people should not be on the road

e.g my nan, she does not know how to turn hand over hand (uses push pull for everything) once she is a lane she wont change unless she has to (so if she has to change into the right lane on the freeway because of a breakdown etc she will stay in the right lane going well below the speed limit)
as much as i love her i have always felt she should not be driving

By the hard way, I mean your death or permanent disability, or worse someone elses...

Motorcycles are not death traps.. It is drivers who are over confident and aggressive on the roads that make motorcycle riding dangerous.. As well as people not checking blind spots and having poor riding skills with no patience an tolerance for others..

Unfortunately, you get these people passing riding sources and getting a bike licence as well..

To say motorcycles are death traps is to say all people that drive sports cars are hoons..

Apart from a good reaction time, you also have to consider the time to put foot to brake + think of what u are going to do.. That is how the 1:5 seconds comes in...

sorry double post

i think the statistics were if you are likely to have a serious motorbike accident once every 18 months
they are not death traps because of the design of them they are death traps because of the lack of respect for them shown by other drivers on the road, i do not try to avoid them because they are bad drivers and i do not trust them just because i know that 1 mistake i do can lead to a death

as for reaction time it does raise more for more complicated procedures however if you are of extremely high intelligence it does not raise your reaction time as much as most people keeping reaction quite low

Can I just ask, what are you basing all of these "facts" on? Where is all your research?

Seriously, this thread is full of so many unsubstantiated claims from you, it makes my head hurt.

Keep on digging yourself deeper.

moved to the Gibberish Corner as it is now just that Gibberish.

and also lets all keep it cool thanks as there is NO need to go head hunting.

Sorry Aza

I toned it down - got too carried away.

I never heard so much dribble before, I suppose you can also leap tall buildings in a single bound and are faster than a speeding bullet?

Mate take a good long hard in the mirror think about your own actions on the road and what would happen if you had a serious accident and killed someone, or maybe that wouldnt even change your attitude it sounds like your a menace on the road with total disregard for your own and others safety. Do yourself a favour and everyone else on the roads and book yourself into a a good defensive/advanced driving course or spend a day with serious crash unit squads might open your eyes
