I can't do anything about the law, but this gripe is mostly about the hassle of printing off the 201V Variation Form, or collecting one from a police station, and taking it back. Who does that nowadays when it only takes 15 minutes online? There's no need for a pen, or a printer.
- Download the 201V blank form first from the PS site (PDF).
- Use free software to convert this into a 'user-fillable' PDF by uploading the download to a free software site.
- Fill it in online, and reload the completed Variation back to that site.
- Download your complete 201V PDF, attach it to an Email, and send it off to your area PS office.
Here's one I made earlier on a Chromebook with the links to do it all online. You can copy & paste your signature in I think, but didn't try that bit.
