Glad to know that you are a hybrid owner asking questions about the LEAF! We transitioned from the Prius hybrid to our LEAF electric vehicle as our daily driver 8 months ago. The hybrid is our college kid's daily driver now (renter, off-campus). The cars work out perfectly in their current roles and we love them both for their purposes! LOL, people used to tell us how awesomely "quiet" the hybrid was. In comparison to the LEAF, the hybrid sounds so noisy when it starts up! You'll love EV driving if you're familiar with a hybrid already. The electronics (key FOB, steering, shifting, braking, etc...) are pretty similar in feel, so the transition is easy. But the EV runs so much cleaner and quieter! And even less maintenance than a hybrid!
Luckily, we don't have to push the mileage limits on a daily basis. So our "rule of thumb" is to charge the LEAF to 80% every day during the "non-peak" electricity hours no matter if we think we have enough for the next day. We will only charge to 100% if we know of plans requiring that. In the 8 mths of EV driving, there was only one occasion in which I didn't charge to 80% (thinking we were gonna have a non-driving day) and decided to get our 3rd car (an internal combustion engine one) parked at grandma's house 5 miles away for car-sharing. This re-scheduled event (due to good weather) included car-pooling with her, so we had to stop at her place anyway.
That would be one option for us in light of an emergency... going to get our ICE car at grandma's. We have a few other relatives that live a couple miles away that can help out. We could also throw our portable EVSE in the trunk (we haven't kept it in the car on a daily basis after the 2nd month or so) for almost-anywhere 120v opportunity charging too if no public L2 available. And if there was an "emergency, emergency, emergency", I think there are enough neighbors on our block that one will be able to help out. Just like we would help them with an emergency car/other issue.
But us finding a ride is totally opposite from the norm. We usually are the drivers when carpooling whether it's our ICE, hybrid or EV. We don't mind driving as it gives the others a break from their ICE vehicles... esp with gas prices lately!
Some people we know like our LEAF and will definitely consider it when they are ready to replace their vehicles. Despite the nit-picking even us LEAF owners are doing... the 1st generation LEAF is built really well. I hope Nissan does well with EVs because they deserve it for pushing ahead with it. It was the same way I felt about Toyota and the Prius years ago. Now, OMG, no worries about the Prii...
