This thread and idea may have developed from boredom, but it seems its already to late to hit the brakes.

I have decided for no other reason that im bored, no one wants to go out and i want to get drunk that im going to test the theory that alcohol severely affects your driving, this test may already be severly flawed due to the fact the only thing i have to watch for is the apex of every corner and not pedestrians and other road users but im quite interested to see exactly how it affects lap times.

the test is simple:

1 track - cape ring
1 car - corvette ZR1 (700bhp, all aids off except 2 ABS & sports hard tyres)
1 contender - that would be me

going to do 5 laps + 1 warm up lap, firstly sober then in 2 can increments. average of the 5 laps will be taken and the fastest lap to see if the lap times are affected.

The track is chosen because it has a long distance, and requires smooth flowing steering and throttle input which i think will really affect me after a few cans. the car was chosen because it requires 110% concentration even without the influence of alcohol

I intend to go upto 6 cans, though depending how tipsy i am after that i may have a couple more.

Just completed the sober laps (well i had 1 bottle earlier but that wont have had a huge effect):

Lap Times (sober):

1 - 2:58:168 (warm up)
2 - 2:56:565
3 - 2:54:765
4 - 2:57:567
5 - 2:55:350
6 - 2:55:286

fastest lap - 2.54:765
average lap - 2.55:827
slowest lap - 2:56.567

Lap Times (2 cans):

1 - 2:56.889 (warm up)
2 - 2:55.305
3 - 2:54.720
4 - 2:58.006
5 - 2:55.135
6 - 2:53.429

Fastest lap - 2:53.429 (-1.336 seconds)
Average lap - 2:55.319 (-0.508 seconds)
Slowest lap - 2:58.086 (+0.519 seconds)

Lap Times (4 cans):

1 - 2:57.212 (warm up)
2 - 3:00.934
3 - 2:56.980
4 - 2:56.697
5 - 2:56.301
6 - 2:54.320

Fastest lap - 2:54.320 (-0.445 seconds)
Average lap - 2:57.046 (+1.22 seconds)
Slowest lap - 3:00.934 (+4.437 seconds)

Lap Times (6 cans):

1 - 2:59.348 (warm up)
2 - 2:58.048
3 - 2:58.702
4 - 2:57.665
5 - 3:06.882
6 - 2:56.978

Fastest lap - 2:56.978 (+2.213 seconds)
Average lap - 2:57.046 (+1.22 seconds)
Slowest lap - 3:06.882 (+10.315 seconds)

I'd be curious to see someone do this experiment with marijuana, I'd be willing to bet it doesn't effect lap times, at least not as much as alcohol will.

cheers guys, just finished painting the rig tonight, will get some proper pics up later on. sank the first 2 cans pretty quickly (approx 25 min), and waited another 20-25 min for them to take affect. At the time of starting the 2nd batch of lap times i felt almost normal, with a very slight light head. The results are as follows:

Lap Times:

1 - 2:56.889 (warm up)
2 - 2:55.305
3 - 2:54.720
4 - 2:58.006
5 - 2:55.135
6 - 2:53.429

Fastest lap - 2:53.429 (-1.336 seconds)
Average lap - 2:55.319 (-0.508 seconds)
Slowest lap - 2:58.086 (+0.519 seconds)

As you can see my fastest lap is over 1 seconds quicker, i feel there are 2 reasons for this. Firstly ive had more time 2 work out my braking points and turn in, but secondly i feel like im being alot smoother with steering input and throttle. This as you can imagine makes a big difference when trying to apply 700hp to the tarmac. My average lap time also backs this up, though the time difference isnt as great. My slowest lap time is actually slower, my 4th lap on both attempts ive tried to give it everything, however that has ended me up on the grass, i wouldnt say this time around my slower lap time was due to an overall bad lap but simply due to me having more trouble getting back on track.

those are really big cans!
there baby 440ml cans, you can also get 500ml and 568ml (pint) cans depending on alcohol brand

EDIT:

also a quick update on drink drive alcohol laws in the uk:

Published sources claim that 6% of all road casualties and 18% of deaths (provisional) can be attributed to an involved party being over the legal drink limit. These figures may not appear high but unless you have been connected in some way with an alcohol related accident it may be difficult to appreciate the implications. Yet, the permitted alcohol limit in the UK remains higher than in eleven other EU countries.

The Effects of Alcohol
We've all heard the term Dutch Courage which means taking risks while under the influence of drink and it doesn't take much alcohol to lull you into a risk taking situation. If you're inebriated and in charge of a vehicle this is comparable to pulling the trigger on a loaded gun. Both provide a means to kill…
Alcohol is absorbed into the bloodstream very quickly yet wears off slowly. It takes just ten minutes for your body to absorb 50% of any alcohol you've consumed; an hour for your entire consumption to enter your bloodstream. The booze you drank last night will still be present in your system more than twelve hours later and no amount of hot coffee will alter this fact.

What Are the Legal Limits?
There are three ways of measuring the amount of alcohol in your bloodstream:
35 micrograms of alcohol per 100 millilitres of breath
80 milligrams of alcohol in 100 millilitres of blood
107 milligrams of alcohol in 100 millilitres of urine
These levels are low when translated into the number of alcoholic units an adult might consume. As a very rough indication, 4 units of alcohol for men and 3 for women is all that is required before you are legally unfit to drive. Compare these units to a single measure of spirits (1 unit), strong lager (3 units), standard lager (2 units) and a small glass of wine (average 1.5 units) and you will realise just how little you need to drink before being over the limit.
The cans im currently drinking are 1.7 units each, therefore after 2 cans ive had 3.4 units. In comparison to whats stated above id agree with their limit. after 2 cans id classify myself as completely fit to operate a motor vehicle

So from this experiment we find out that drinking and driving makes you go faster? D:

Once you've played WoW for 3 years, you find out that having half your raid drunk will dramatically improve your performance as a team ;).

This is a great experiment though Mr.T! I envy your set-up too :(.

4 cans down and another 5 laps, this time the drink has taken an affect! after 4 cans im currently at 6.8 units, 2.8 over the legal limit. do i agree with the alcohol limit..yes i do. Heres the lap times after 4 cans:

Lap Times (4 cans):

1 - 2:57.212
2 - 3:00.934
3 - 2:56.980
4 - 2:56.697
5 - 2:56.301
6 - 2:54.320

Fastest lap - 2:54.320 (-0.445 seconds)
Average lap - 2:57.046 (+1.22 seconds)
Slowest lap - 3:00.934 (+4.437 seconds)

as you can see my fastest lap is actually faster than my sober lap, though it was done on my final lap. prior to this i definitely wasnt in the zone. lap 2 was an absolute shambles. i felt far to confident, even after out braking myself several times and completely missing the apex's i still felt i was jonny big balls, this ended up with me over 4 seconds adrift from my initial slowest time. after a few laps i returned to an acceptable driving style though i was nowehere near as smooth as after 2 cans, i found myself kicking the back end out on quite a few corners and generally missing my braking points. though i did put in a quick lap it took i was driving like a complete idiot with far to much confidence , this i feel is where the danger zone is for people that have a couple to may before jumping in the car.

Kinda funny, i have been thinking the same this week when i played after taking some drinks.

I dont have the exsact times, but i played driving the Zonda yesterday after 1 bottle of wine and my laptimes where challenging the standing best time.Few days before i had about 6 glasses of Ballantines and the times where allso competative. I dont think drinking will effect my driving as long as i can keep the focus, something i even might find easier while drunk.
I think where drinking really would standout are more multitask orientented games like starcraft or real driving for that matter.

6 cans and another 5 laps down and the results speak for themselves:

Lap Times (6 cans):

1 - 2:59.348 (warm up)
2 - 2:58.048
3 - 2:58.702
4 - 2:57.665
5 - 3:06.882
6 - 2:56.978

Fastest lap - 2:57.665 (+2.90 seconds)
Average lap - 2:57.046 (+1.22 seconds)
Slowest lap - 3:06.882 (+10.315 seconds)

This proves everything it needed to. Alcohol affects your driving skiil, though that may be obvious until this test it wasnt clear exactly how much of an affect alchol has on someone's ability to drive. In a way this test is subjective as everyone reacts differently to alcohol but id like to think i can handle a regular amount, as much as the average joe anyway. Though i could continue this test i see absolutely no reason to. I have set out to prove alcohol affects driving and i have proved that.

My driving senses throughout the test have deteriorated, from knowing exactly how the tyres are reacting with the road surface it has gradually got worse to the point that accelerating out of corners has often left me sideways and struggling to regain traction. I dint hit a barrier until the final test, at which point i hit several trying to chase down a fast lap.

Though im fully aware drinking alcohol affects your driving tonights test has actually suprised me as to how much. whilst my average lap times havent hugely different my ability to judge a car on the limit has, and add to that the substantial increase in confidence as the drinks were downed its all adds up to a recipe for disaster!

440 ml = 14.88 US fluid ounces. so i guess they are almost equivalent to 16oz Tall boys!! I might do some research of my own tonight! GT5 drunk driving simulator!

I can confirm that a bottle of wine and a little herb greatly enhances my in game driving skills, but with some of the wrecks ive had I wouldn't want to try this in real life lol!

Tis a G27, Tv is a 37" Hitachi and ive got the onkyo SR308 with tannoy SFX 5.1 speakers. Nothing to special but does an exceptional job tbf, not looking to change anytime soon.

Just chucked all the results into excel and got the following graph:



aside from the single lap spike it seems that driving skill is inversely proportionate to alcohol intake.
