A few seconds last you two days of driving? Do you only drive a mile a day? 10 miles? 30 miles? You are giving us an emotional answer to make you feel good about your car... Which none of us really cares about. We want to know how good is a charge that is about the same time as a gas fill will give us on an electric car.
No we don't. With gas, cars must be supervised during the refueling process for safety reasons so refueling time is important. With electric you don't need to stand there and watch the car recharge, you can go off and do something else so the charging time is not wasted just standing there. Where I live (Montreal) malls, community centers and offices provide charging stations. This means the car can be charging while I'm at work, at home asleep,or while I'm eating/shopping etc so the time is not wasted the same way that if I were stuck standing there for the entire refill time.
