Situational awareness is an entirely different story though. In the dead of night traffic is on easy mode, where you notice the indirect illumination of a car's headlights around two corners and hear them from a mile away. That's just not very challenging (and probably plays a large role in the seemingly universal pattern of more drunk driving in rural areas, unfortunately cars come with an incredible amount of risk compensation through speed). Broad daylight city cycling on the other hand I consider a bad idea even at BAC levels well within the legal limits for driving cars (speaking of Germany here, where in terms of fines, cycling is tolerated at twice the BAC level as driving, a reasonable compromise)
