The thing is, it didn't have to happen. Families are torn apart due to negligence. If it's dark, anything past idle is too fast. Prayers to the families.
If it's a lake that I know I will go faster than idle down the lake at night. I use extreme caution and never run wide open or wot. Idle is not really a good option on busy lakes even after dark as it puts you in the middle of the lake at a very slow speed. If I don't know the lake I get off of it in plenty of time to not worry about that. I also use gps and waypoints to help out. They will keep you on the right track back to ramp etc. I will say while I am by no means an expert in the boating field there are far to many people on the water that have no business there and are dangerous during the day time and extremely dangerous after dark. It's a horrible end to any baiting trip and one that I hope everyone can avoid.
