Naturally it doesn;t account for cloned IDs or banned drivers, but it's a start.
Turns out it's been thought of before https://www.theguardian.com/government-computing-network/2012/mar/16/anpr-petrol-stations-uninsured-drivers
After my tweet was brought to the attention of the PCC national lead for road safety, I emailed her office. Below is the somewhat dismissive reply from here office
The use of ANPR is strictly controlled to protect the rights and freedoms of the public.
I am afraid I have been unable to establish whether the proposals suggested by Ernst and Young in the Guardian article went anywhere. I suspect that the restrictions on the use of ANPR are one reason why they did not. I am not aware of any current thinking of this type in this area.
If a petrol forecourt uses a camera recording system to identify vehicles that make-off without payment, this will ultimately assist their company’s bottom line. To use this as a means of detecting a vehicle that has no tax, insurance etc would not be of a financial benefit to the garage. However, it is conceivable a garage may wish to enter into a voluntary arrangement with the police to detect vehicles which were not insured etc if this were permitted. The unintended consequences of this approach would need thinking through. For example, if it was known a garage deployed this technology and word got around– motorists may well boycott it – losing business for the garage.
I am not an expert on such matters but I would question the legality of restricting the sale of petrol/ diesel to a motorist because their car is several days beyond its MoT renewal date.
The police already use ANPR to detect vehicles that are not compliant with road law. This includes ANPR situated in police vehicles to detect vehicles when they are out and about.
I have passed your comments through to the National Police Chiefs Council to make them aware.
Many thanks for raising this interesting point.
So that's a no. Yet we have filling stations using same ANPR to penalise drivers to stop longer than an F1 pitstop https://www.theguardian.com/money/2019/nov/23/driver-fined-100-at-bp-for-taking-too-long
