Drinking, then drive.
Well, in my opinion, it is ALWAYS BEST to NOT DRINK and then drive.
But the following does make some difference:
>> Drink a few beers, then drive some two hours later
>> Drink only one can of beer, then drive an hour later
>> Drink some hard stuff ( whisky / brandy etc. ) then drive
3 hours later
But in any of the above options, if you drive after some drinks (
hours later ) and get involved in an accident, you're still in
trouble.
What I do; drink a lot, then get my wife or friend to drive me
home. The best arrangement if you wanna enjoy some drinks.
Alcohol makes a motorist OVER confident on the road, and skews your
judgement. Reaction also slower.
