Round here, very little has changed in the last 3 years in regards to charging infrastructure (or much else come to that – our council appear to be allergic to anything up to date and hark back to halcyon days of the 60s all the time ), I’m not too hopeful for the next 3.
However, even if they improved the infrastructure, there will still be the issue of cost. Public charging is not cheap, in fact it is blooming expensive and that, I fear, will not change as there will be the captive audience of those unable to charge at home. A year ago, there were a couple of free chargers that could be used within 10 miles of here, now there are none.
