some of that is down to manufacturers to fix thought we are waiting for google/waze to fully integrate API charger status information,
and car manufacturers to either see the native Android Automotive light (like renault/polestar did) or invest correctly in their home brew nav/charge systems,
my parents wouldn't want to be playing with apps on a phone.
i agree this is part of the issue, a lot of cars already have this ability (though i cant attest to how accurate they are) but this often involves extra subscriptions which are really not cheap and barely worth it if only needed a handful of times a year.
the main issue however is, we really should not need an app to tell us if a charging point is actually working or not. Some companies are worse than others but the expectation should be that charge points work..... simple as that. I dont worry if a BP pump is working or not, because i know 99.9% of the time it will be. Sure once in a blue moon i get there and a pump may be out of action. or maybe even they ran out of petrol. At which point i moan and move on........ but this is really really rare and i can be certain that if this happens the next one will definitely be working.
having live information on the availability of charge points is a very nice to have feature...... but part of the reason they are needed is because of poor maintenance, they are minimising the symptoms but not really addressing the main cause.
in truth if you stick with major charging hubs its generally not an issue, and there are enough of them around that for most people with a high range car you can just use them on a long road trip..... it is the smaller local ones with only a couple of DC chargers or destination AC ones which tend to be a bit crap, which is unfortunate because for many it is those smaller ones which are needed, esp for those without home charging (not me thankfully)
The EV "problem" is very different for those with the ability for home charging and those without. Those with it, it is pretty easy to avoid problems, but for those without i see why they are reticent to go electric.
I just came back off my hols and whilst there i was chatting to a Londoner who lives in a flat. No chance of him home charging, but he did say there were a lot of roadside charging points, which is great and everywhere needs them not just London.
BUT he said they are almost always taken up by taxi drivers/uber drivers and it would not be something he could rely on. I cant speak with experience of this personally but i have no reason to doubt him. Maybe taxis/ubers should be blocked from using residential charging points?
