I was taught to put the console through the BC, under my arm and positioned so that the gauges were showing with just a need to glance down, I still dive this way and can always take a quick look at my gauges. I also dive with my left hand holding my right wrist so my DC is also in an easy to see and read position at all times.
Just like driving where I scan the measurements every couple of minutes I can and do check my DC and gauges every couple of minutes. I am not using an air integrated computer, so I do a quick mental calculation on my air consumption to see how much time I have left and to track my progress.
It is not the presence of a DC that encourages risky behaviors, do you really think that someone who learned on tables cannot ignore the dive planning and thinking about what is happening? Did no one do risky dives before computers were invented?
It comes to training, I was lucky I had good grounding in the basics on my OW course. Constantly checking gauges was drilled into me. I am an engineer and also once took a private pilot course, safety, redundancy and constant checking, then thinking through what the instruments are really telling me, are just part of what makes me tick.
In young engineers I see an over-reliance in technology, if the computer says it then it must be true, no allowance for GIGO ( garbage in garbage out) or a failure of the technology. New and young divers are the same.
I came up when the technology was unreliable and still look for multiple confirmation on critical information.
I am just out there to have fun, blow bubbles and look at the pretty fishes. I am not out there to prove anything to anyone. I set my computer to a conservative profile and avoid going near the NDL. I would rather come up 5 minutes early with 100 bar air in the tank than risk getting bent.
If I see a diver exhibiting risky behaviors I will inform the DM and let them deal with it. If the behaviors continue I may ask not to be grouped with that diver, I will refuse them as an instabuddy. It has never happened to me yet but in extreme cases, where the DM and dive operator refused to take corrective actions, not to protect the bad diver but to protect me from the bad diver, then I would simply find a new dive operation to dive with.
