Leasing EVs would be a loser to those leasing companies,
since, most people will stay away from them, and, they would necessarily be more expensive to lease, because, they are more expensive to purchase and maintain.
Also, nobody who leases would want to have to maintain a charging station in their home for a temporary contract, and the only other way to recharge the vehicle might be to travel to the leasing company for a recharge, or to an out of the way charging station.
Not too practical. Not yet.
