It's stressful enough to operate these items, but far more difficult to operate a motor vehicle with these cockpit distractions. I often wonder when we will have mini-nuclear plants in the trunk to produce enough juice to run all of this stuff.
When I came on all we had was the radio and lights-and-siren controls, heck we did not even have an AM/FM radio in that old beat-up city unit. So, you listened to the police radio for that was all you had. I do recall my FTO days; I wouldn't allow the recruit to listen to AM/FM until they had mastered the police radio.
These are yesteryear techniques. I recall the coppers of yesteryear, who claimed that they could drive on a code run, drink coffee, smoke a cigarette and talk on the radio at the same time. This may be done once, but you can't do it all the time. Adding today's cockpit equipment, it's an urban myth now.
My greatest concern for the FTO and the recruit is that we are having more and more motor vehicle crashes and police officer deaths from crashes. I often wonder what part these new electronic additions contribute to this.
We have constant reminders to the civilian motoring public not to text and drive, talk on the cell phone and drive and don't even think about messing with the entertainment systems. For me, the mobile data terminal is the most distracting.
