Of course a giant company like Volkswagen won't turn around on a dime, it will be a slow transition; and probably never a complete one.
But just from the fact that electric cars have a 5 times higher share of new registrations than of existing cars shows that it's a growing market, and adoption curves usually grow exponentially until you approach market saturation. Volkswagen is doing a lot to get a bigger piece of that pie.

Yes, there is a long tail of applications where EVs are not a reasonable proposition. Emergency services (police, medical, fire fighting) come to mind immediately. There is pretty much no way you can built an all-electric fire truck with batteries that isn't much worse than ICE fire trucks today: Battery weight means you can carry less water, which directly reduces operational capability; limited battery charge means the truck's pumps don't last as long, and a battery is much harder to refuel in the field than a tank of diesel. Similar reasons apply to ambulances. Some L.E. vehicles can reasonably be made to work as EVs (patrol cars), others not so much. Whenever you need to maximize off-grid operational time or you continuously need a lot of power, EVs are just not a sane option.
Additionally the small number of these vehicles make their emissions rather irrelevant.
Most fire trucks in Germany would actually work well as EV: they rarely carry water, just pumps (places without hydrants are required by law to have water stored in a tank or lake); range isn't an issue since any place is reached by emergency services in under 10 minutes, even accounting for large scale operations that's not a lot of distance unless we are talking highly specialized vehicles; and the better acceleration of EVs might be a major speed boost. Similar reasoning applies to ambulances: small distances but high acceleration requirements.
Of course in sparsely populated places like much of the US this looks completely different. Another class of vehicle that will hold onto ICE for a long while will be farming vehicles. I don't see a farmer recharging his combine harvester in the middle of the field until we have made significant advances in battery tech.
Tanklöschfahrzeuge normally do use their internal tanks, at least in my area. This makes sense because it reduces response time and you can start pumping out water immediately while the connection to the water line is made.
The problem is not so much the driving range, that is true. The problem is that taking out a fire might take 10 minutes, 10 hours or 10 days. The electric truck is fine for 10 minutes, but it won't be fine when you have to stay on site for a couple hours.
