Since the Bolt can fully charge in 8.5 hours on a L2 charger I'm not sure faster charging is needed for the majority of homes.
It’s not about being able to charge at home. L1 or L2 charging is fine for home recharging for daily commuting.
You might have no need for high speed recharging at home, but my point is that even if you wanted to, you could not. For most people, high speed recharging will never be affordable or feasible for home charging. The usefulness of fast charging lies elsewhere.
Why do people pay restaurant prices or even fast food prices instead of eating at home? To save time? To get a dining experience they can’t get at home? The kitchen is being remodeled?
And for those times when you’re not at home, what do you do about eating? Seek out a restaurant? Make do with the microwave in your hotel room?
Think of a high speed recharging station as the automotive equivalent of a restaurant. What’s a good location for a business whose customers are seeking to refuel their vehicles quickly? Somewhere where the drivers have other things they want to do with their time...
For example, your family has just arrived in at a resort / theme park / travel destination area for a week’s vacation... fully recharging the car will give you enough fuel to take care of your around-town driving needs for the week, so you want to get it done quickly... what are the choices? An 80% charge in 30 minutes? A full recharge in 10 minutes? Certainly it’s going to cost more than it would to recharge overnight at home... If there’s a recharging station in town that will do it in 30 minutes, I’m willing to pay a reasonable price, and perhaps a little more if it can be done in 10 minutes while I wait... And when the week ends, another 10 minutes will fill my tank for the trip home...
Keep in mind there is a difference between a restaurant and a grocery store. A desire to refuel quickly is not the same as a need to refuel, and dining at a restaurant is not the same as grocery shopping... a charging station serving those who can’t make it home without more fuel (or don’t have fuel at home) has a different customer base than a charging station serving those who are temporarily away from home.
