That makes sense... to have their SC clogged with Bolts would be really bad. However, I think it would be fair if Tesla allows 1/4 of their stalls to be used by non-Tesla instead.Yes it can, at about 55 kW peak.
Which was my earlier point. Tesla will not agree to a charging arrangement with cars like the Bolt because they charge too slowly. For Tesla it is a QOS thing; they do not want the congestion.
