Auto Express seems to be the source of those figures, which show that diesel cars as a class have (slightly) higher average mileage than Teslas, and roughly 33% higher average mileage than full electrics as a class. Again, it seems like selection bias, in that those high-mileage drivers who can use electric do, and those that can't buy diesel. Presumably there is a cohort of diesel drivers who would switch to electric if they offered sufficient range or faster charging, especially as diesels outnumber electrics ~2.5:1 in the UK [2].
