Three numbers, and whether to believe them.
Every fleet vendor has a case study with a big percentage in it. These are ours, taken apart with the same models the rest of this site publishes — including where the headline is softer than it looks, and the customer it did not work for.
SAR 2.1M of fuel, and most of it was not theft
We suspected siphoning for two years and could never prove it. The first month of tank telemetry gave us four depots and eleven vehicles.
They bought for the siphoning. 11 trucks at 4 depots is 1.8% of the fleet, which is what theft usually looks like: a few people, not a culture. The larger saving came from engines left running for air conditioning, which nobody had thought to count.
- Fleet fuel bill, 620 trucks at 31,280 L each
- SAR 32.19M
- Recovered, as a share of it
- 6.5%
- Idling, at the model's 4%
- SAR 1,288k
- Theft, the remainder
- SAR 812k
The remainder works out to 2.6% of the fuel left after idling. Our model assumes 2%, which on this fleet would have been SAR 618k. So theft here ran about 31% above our conservative rate — believable for a fleet that had suspected it for two years, and not a number to expect on yours.
Fitted: Advanced unit with a fuel probe on every tractor.
31% fewer collisions — somewhere between 6% and 49%
The in-cab warning does most of the work. By the time a driver reaches coaching there is usually nothing left to coach.
Two counts of about a hundred are noisy. The drop is real — the interval clears zero — but only just, and 6% is as consistent with this data as 49%. The programme also started after a bad year, and bad years tend to be followed by better ones whatever you do.
Would you see it on your fleet?
This result is visible because the fleet is 1,400 vans. It would have needed 1.4 years of baseline to be seen reliably even there. Move the slider to your size.
At the reference rate, a fleet this size has about 14 at-fault reportable collisions a year. The years are how long a baseline has to run before a drop this size shows up four times in five, at 5% significance — the same test the safety page uses.
Your collision count will not tell you whether it worked in time to matter. Manage the leading indicators instead, and treat a result like theirs as evidence about the method, not a forecast for you.
9 days, with no day to spare
Fitters came to our yards on our shift pattern. We did not take a single vehicle off the road for it.
4 fitters, 8 Wired units each per 8-hour night once walking the yard is counted. That is 32 a night, 8 nights of fitting and 1 day of survey first. It fits the nine days exactly. One night of rain or a batch plant running late and it would have been ten — which is why we quote two weeks.

Bright: fitted that night, up to 32. The last night is half a night, which is the only slack in the plan.
The fitting arithmeticThe one it did not pay back for
45 light pickups, the entry plan, bought to cut idling and nothing else. They left at the first renewal, and on the numbers they were right to.
Light vehicles burn little fuel, so a 4% cut of it is small, and one lever cannot carry a subscription. We should have said so before they signed. The cost calculator now does, for any fleet shaped like this one.

Why there are no logos here
Across 41,600 vehicles, most customers would rather their fuel losses and collision counts were not a vendor's marketing. So stories are described by sector and size, and a logo appears only with a signed reference behind it.
Ask for the reference call
After a demo, we will put you on the phone with the person quoted, under the same confidentiality you would want.
Ask them what went wrong
Every rollout has a week that went badly. A reference who cannot name one was coached.
Ask what they switched off
Alerts nobody read, reports nobody opened. What they stopped using says more than what they kept.
Ask about renewal
Whether they renewed, at what plan, and whether the fleet on it grew. That is the only number we cannot write ourselves.
