I have a Tesla S85 and Tesla's 80A charger (on a 100A circuit because of the safety margin you mention). I don't normally have to charge my car quickly, but there has been a few times have 80A available has come in super handy. To install the 80A charger, I had to upgrade the service panel on my house from a total of 100A service to 250A service. I also had to have a dedicated 100A circuit line run from the panel to the garage. Thankfully, I was able to do that using the same service line to the house that I already had. However, the power company wouldn't let me go higher than 250 without significant cost and time. Anyway, all that is to say, I LOVE my 80A charger, and you'll have to pry it from my cold dead hands.
