But telling them that they must install an EVSE in their garage which supports the maximum charge rate of their EV could be potentially causing someone to spend thousands more than they really need to. If you are running a new circuit, sure, run the thickest wire you can.
On the other hand, there are plenty of existing homes/apartments/etc with access to a simple outlet (maybe 15A/120V, in my case I had 20A/240V, so I have a 15A/240V EVSE in my garage) but running a new circuit could cost thousands. For those, I would encourage them to consider their actual needs, and not just run out and install the best they can because someone asserted that it is "the only way to go".
Yeah, how far you drive on a typical day is a very important factor in your charging requirements. If you don't drive very far each day then you may well be able to get away with a much lower charger rate. And if you normally use "hilltop reserve mode" then that also reduces your charging time.
I have 240V/30A panel in my garage and nothing else there aside from the lights and the door opener, so I could install a 20A L2 charger for minimal cost. The run to the garage is buried so it's potentially quite expensive to upgrade (although I haven't asked for an estimate so far). At 20A I should get at least 4.5KW of charging power, which would translate to no more than about 15 hours to charge from empty. That would only become an issue if I need to do full-range drives on two consecutive days, which I think given my driving habits is unlikely enough for me to live with.
My expectation right now is that I'd probably keep the Bolt charged to "hilltop reserve" level, so another question for me is "how long will it take to top up the final 10% if I decide to go on a long trip". At 20A it should be about 90 minutes or less, and that also seems like something I could deal with pretty easily.
