Getting married has lots of benefits, including gaining a few family members, in this case a nephew.
So he turns up with his first car, a half tidy Toyota Yaris, £300 for the car, £1600 to insure it. He said he has to have a black box fitted but doesn’t know where, when or why. His mum asked if I could help and said bring your documents and I will get him booked in somewhere, I had read that they squirrel the device away behind the dash, inside a door panel or under the steering column.
The nephew arrives proud as punch, the first time he has driven on a busy dual carriageway and the first time he has put fuel in a car on his own, he hands me this envelope and a small parcel. I was expecting having to book him into Quick Fit or something like that, but no, its a sticky pad, two wires to the battery terminals and an instant activation text to his phone, it took longer to open the bonnet than to fit the device.
Like a proper bloke does. I then read the documents, it said you may want to employ an engineer to fit this device, they will probably charge an hours labour, around £60.
I so wish I had been an engineer. 
Yeah seems insurance companies are doing it on the cheap these days.
My friends lad has his first one fitted by a mobile fitted from one insurance company. Second one was juts sent out in the post as you say with sticky pads and two wires with instructions to attach it to battery box.
As with all these devices they monitor G-forces, and speed via GPS.
These new generation trackers run on the 5G network. They talk to the car by WiFi so they can interrogate the car for it`s VIN code, and detect if it is removed, or fitted to another vehicle.
By GPS it can tell if the driver has been to a high risk area, such as a pub, and if the driver is under 21 it will send an automated message to their parents. Some models will immobilize the vehicle after midnight when more accidents with young drivers occur*.
Being 5G the vehicle is watched by agents in China who must file reports if any vehicle takes a sharp right turn.
*unless authorised by a fairy god-mother.
The bad ones will still crash.But the difference is there’ll be none of them who can then actually handle a proper car at even 7/10ths in the right place at any age because they won’t have the experience.Because they’ve all been forced to drive like their granny everywhere.
One problem is they sometimes get the speeds wrong on roads and it can be a pain trying to get them to understand this.
