@Nahlem, answered everything correctly from my point of view. I'll give you some short answers to your questions as well.
0-50 every red light is a race waiting to happen even though the other person doesn't now there's a race going on.
With the modes
EcoPro/EcoPro+
Comfort :I use the only on local streets
EcoPro :75mph freeway Pro+ driving crazy over 80mph
battery in winter: you do loses 5-10 miles
Had my i3 since 2015 the only thing that I change was the battery 12v ....
And every year rear tires!!!
And every year looks like I lose 2-3 miles since it was new.
