It is what it is. We wait in lines for gas, groceries, restaurants, doctors etc. If anything Americans are impatient.
Do we?
Some order groceries from delivery services. Or we order ahead and park in the designated spot and have someone bring them out to the car.
Are we impatient (yes some are) or do we value using our time in other ways?
This is one of the advantages of being able to charge at home. If one has the ability to charge in their driveway or garage, that is time not spent outside of the home charging or fueling. (Also one of the disadvantages as fueling quickly doesn't impact the life of the fuel tank like rapid charging can degrade the battery system.)
For some, the extra time spent charging in public is more than offset by the time saved NOT fueling every few days, etc.
As I mentioned in the other thread. A trip to Gas Pro Shop (Buc'ees) might be 15-30 minutes as that's a destination, so getting a full(ish) charge in that time is feasible.
In day to day use, slower charging is adequate and likely a winner as it doesn't have the same impact on the battery.
Fast charging is, IIRC, a way to reduce battery life.
Okay, I admit, I'm straying from the question a bit, while trying to point out the relative advantages and disadvantages. For longer trips where charging is needed, I'd think 30 minutes every 3-4 hours of travel (180-240 miles) would be about the max folks would want to spend.
More likely 15 minutes with an added 200-250 miles of range.
With the understanding that the faster the rate the battery can be charged, the greater the negative impact on battery longevity.
