Its a fair question. I boat drove drunk many times in my 20s. Its not right to do obviously, but traffic-wise, the amount of space you've got, it IS much easier to navigate. In the day. Knowing the water you're in helps too. Plus, you SHOULD have a natural cautious tendency that slows you down anyway, on some level. Nighttime? Man, its a different story. I don't care how often you've been in an area, you can't go blindfolded thru it. And those guys were NOT even familiar with that waterway. Fast speeds, at night, not knowing the layout? It'd take true idiots to be doing that.....
