Cant think of anything more horrific....having complete strangers turning up on my drive to use my charger, knocking on my door with their kids that need the toilet, and other not so pleasant people peeing up the side of my house, pulling in more traffic into my nice quiet cut-de-sac, and living near a couple of large A roads would probably pull in alot of passing traffic with the risk of having people queueing up outside my house and me apologising to my neighbours. What a horrific idea.
Generally other people are badly behaved and not particularly pleasant. I've seen enough shenanigans when using proper charge points out and about...people dumping their litter on the ground, letting their dogs out to foul the surrounding area, general hanging around smoking and vaping and a whole host of other unpleasant behaviour. At least in petrol stations it only takes a few minutes to fill up, pay and sod off so people tend to stay in the car rather than get out and start being a PITA.
As for EV's catching fire...yes they do. not particularly common, but they do and have. Mine has never spontaneously combusted and I don't know of anyone's who has, but they do. And more recently in Australia a massive battery farm caught fire, like the ones were ivensting billions of pounds in building in the UK. The problem when EV's catch fire is putting the fire out...there has been at least 3 large car ferries full of brand new cars being delivered somewhere go up because of an EV spontaneously combusting, only one of which hit the mainstream media, and the only option they had was to anchor the vessel off the coast and let it burn out. Yes ICE cars do catch fire but most of the fires are latest generation diesels that have been festooned with so much complicated technology to bring their emissions down and it is that technology that usually is the root cause of the fire...usually the Exhaust Gas Recirculation Valve gumming up with soot and combusting when the engine goes into a routine regen cycle, so actually nothing fundamentally to do with diesel engines, but all the complex expensive tech that is needed to comply with emissions regulations.
Just to highlight that the problem of spontaneously combusting batteries, the Boeing 787 was the first aircraft to use Lithium Ion batteries instead of more conventional batteries and in the first few years of service there were several cases of batteries spontaneously combusting, like small ones too that power smoke alarms, and in some cases resulted in the loss of the entire aircraft. Thank god it never happened in flight (though there has been cases of laptop batteries combusting during flight which is why you cant put them in the hold) and all incidents were on the ground. The entire global fleet was grounded and Boeing had to roll out a fix pretty quick and the cost of millions of dollars and included a redesign of the batteries and charging systems and encasing the batteries in heavy armoured boxes to contain and safely vent the fire - so still cant guarantee they wont combust so had to design the system to contain a battery that does. But this never ever ever happened ever in the history of commercial aviation with the older tech batteries. So there is an issue with Lithium based batteries that has to be considered in the design of the system to contain and prevent thermal runaway...you cant deny that. Not saying there is not a technical or engineering solution available, but until those solutions are all available and rolled out into the entire fleet of cars/ships/aircraft/ground based battery stations etc. then it will always be a risk.
