There's all sorts needs sorting out. For instance, SWMBO and I have just had a week in the Lakes. To get there from here is 300+ mile, 4/5-hour drive. Call it a tank of fuel there, and another back once you've done some running around at the top end.
At present, even given my small and frugal car, call it 2 x >£60.
I can't do that journey for similar money by, for instance, using the train. The fares cost too much, the luggage-stowage facilities are shocking (we no longer have guards' vans), and there's no easy onward way of moving from the station to where we were staying - not with kit and provisions enough for a week.
'Integrated transport' is yet working, then. In fact, it doesn't exist. I could make a sideways point here about parking charges up in the Lakes but I won't; suffice to say the local councils up there are on a very good screw...
If I were hiring a car for that journey at this stage, and travelling in future might require that because there are an additional two elderly people involved, it wouldn't be electric. It would likely be diesel.
I'm not saying that the solutions are there yet. The work to deliver them is ongoing, though.
