Tesla wins on charging because Superchargers are ubiquitous and they just work: you can pull up to one and be pretty much guaranteed that you'll be able to charge. This is manifestly not the case for any of the competition.
Afaik it’s the same in US, isn’t it? Just with the complication that there’s no government mandated standard, but NACS seems to becoming the de facto standard? So a benefit to Tesla for older models I suppose?
I'm setting aside that charging off of public EVs is relatively rare anyway... but your premise is flawed.
