Usage patterns is only one criterion, there are more such as…
One needs look at distances in conjunction with battery charging cycle times (both total trip lengths between recharges and frequency of recharges). The opportunity for (as some destinations may not have charging points) and speed of recharging is possibly the last criterion.
There has been also talk of a car/vehicle sharing future, which if eventuates, is another complication as vehicle use/distance per day could increase substantially for each vehicle on the road.
