Haven't read all 8 pages, but I've noticed a number of posts excusing the lack of compliance with this law on grounds of supply issues but the reality is, every operator has known about this for a few years now, if they all leave it until the last minute, of course there will be supply issues.
The rules were announced 3 years ago (March 2023). The law came into force in October 2023, and the first wave of buses (those registered on or after 1st October 2019) due to comply was October 2024. That was a year from the law coming into force, to the first buses needing to comply.
I don't believe there was any prior warning or specific consultation on the legislation either so the industry didn't even get a heads up. It was just overnight, a random day in March 2023, Bam here is a set of rules tens of thousands of buses need this new system fitting and programming within the next 3 years. In that time, there has no only been a lot of places trying to work out what is in/out of scope, but also what it means for them. There's around 30,000 local buses, plus then you have to consider coaches for any in scope schools/colleges as well as all vehicles on rail replacement (because many train operators are misunderstanding the rules surrounding what is in/out of scope). All of which, by the book needed to comply within 3 years of the law being introduced. That's a hell of a workload for ANY industry.
Then you look at the UK supply chain for this sort of thing, and your options are basically 2 suppliers and a few random ones that no one really use. It's a hell of an overnight upscale, with no prior warning. Even if we had all of the parts, there just isn't the staff. And if NSA companies upscale, so must their suppliers. And all of this is for staff who, if they upscaled to the rate needed, would probably not be very good (mass intensive training doesn't tend to produce many high quality staff in any industry) and would be out of a job within a few years and then Hanover and Mobitech would have a lot of redundancies on their hands.
PSVAR there is no excuses, people had 20 years notice for that and still when the deadlines came, everyone acted like it was a surprise to them, especially in the coach sector. Yet far more vehicles need to comply with PSVAIR, and there is a 1-3 year timeframe to comply. With tens of thousands of buses, using only a few suppliers. I think any civil servant and politicians who drafted this legislation had their heads in the clouds in terms of the scope and the deadlines.
programming issues. None of it is simple!
Worth noting the fact that many operators are/were relying on enthusiasts to do their destination blinds for them in the first place. And while this is by no means easy, it's the easy part now compared to the rest of what needs sorting. Every variation of every route, needs it's own destination code, blind, stop list, announcements. All set up to trigger at the right times, with the right pronunciations. It takes absolutely ages to sort.
