The Question to Ask First

Most arguments about driver monitoring are arguments about features. One question moves past them.

The question

What would we do differently if we knew this?

Ask it of every measurement, every camera direction and every report.

What the answers mean

"Coach a driver about a specific event." A real action, provided the review process and the time exist. Proceed.

"Defend a claim." A real action, and the strongest single case in this field. Proceed.

"Find the junction that generates events." A structural action, and usually the most valuable thing the data produces.

"Know who the risky drivers are." Ask the follow-up: and then what? If the answer is a ranking, the data cannot support it. If it is a conversation, that is coaching, and the score is not needed to start one.

"See what the drivers are doing." Not an action. This is the request that produces live cab viewing, and it should be declined.

Why it works

It separates the operational from the anxious without anyone having to admit which they are.

It identifies which features are needed, which is the configuration decision, the retention decision and the proportionality argument all at once.

And it reduces the specification, because most of what a platform offers informs no action anyone will take.

The second question

And what happens when it is wrong?

A false trigger reaching a coaching conversation costs a driver's goodwill.

A false fatigue alert reaching a disciplinary process costs a case.

Every measurement here has an error rate, and a feature whose failure mode nobody has considered is not ready to enable.

Using both

The first decides what to collect.

The second decides what weight it can carry and what process must surround it.

Neither requires buying anything.

The collection in one line

Measure the few things that are measurable, act on them quickly and privately, fix the structural causes the data reveals, and never rank a person on a number you cannot explain to them.

Everything else here is the detail of doing that.

Ask it of every camera direction

Not only of the purchase as a whole.

Forward: defends claims and establishes incidents. A clear action.

Rear and side: prevents manoeuvring collisions. A clear action.

Cab: what would we do differently? If the answer is fatigue intervention with a documented risk, that is an action. If it is "see what they are doing", it is not.

Running the question down the list usually shortens it.
