Most Guardian articles involving anything technical are very inaccurate!
Some diesels are likely much worse for particulates and NOx (higher compression) than petrol?
Anyway, it's not simple. I find it hard to believe a Tesla is simpler than my petrol Toyota Yaris. Logically hybrids must be the most complex? However I think an EV ought to be mechanically simpler. Two or four motors (at the wheels, which I saw a design for in 1970s) also would remove more mechanical parts. The differential, drive shafts and gearbox is a lot of mechanical weight and mechanical complexity, especially on 4WD.
You'd think ULEZ is costing every motorist a fortune according to some reporting, but other reporting suggests only about 12.5% are liable. However it seems it will save lives in London.
The remaining pollution issue for EV, apart from manufacture, is tyre particulates. Perhaps there is scope there for improvements too.
