"Dieselgate wasn't about particulates, and unlike petrol cars every diesel car of the last 10-15 years has a particulate filter..."
Not true here in the UK - I buy and sell secondhand cars of this vintage as a side job, and not all the diesels I've seen have DPFs (I'd say it was 50% have them) - lots of models didn't have them, including quite a few vans (which pollute more due to bigger engines, lower mpg, etc). And anyone who's bought anything of this age range also knows that the DPFs are a reliability nightmare. Lots of people removed them (which is now at least tested on the MOT, although it's possible to remove it in a way that is not detected by an MOT test).
But most importantly, although dieselgate wasn't about particulates, it still means getting diesels off the road, which is a good thing. If particulates had been accurately measured in vehicles after a few years, I'm sure many more would be off the road, particularly 1st gen DPF cars.
The problem is that most people now equate a vehicle with a DPF as being a nightmare, and then by association don't care about the effect on the environment as the effect on their wallet is a more pressing need. Much the same as EGR valves, which are a reliability issue on most vehicles regardless of fuel. People block them off, leading to increased NOx pollution and better fuel consumption, and when it can cost hundreds of pounds to get it replaced (if it has to be calibrated to the ECU, etc, often a main dealer trip is involved), it's not surprising that this happens.
The sooner we can all go electric, the better, IMO. And I say that as someone who has considerable skill and experience in repairing and maintaining ICE cars.
