hi all, question about charging at home. Does the R1 come with a "charging cable" similar to the Tesla cars? Or is the only way to charge at home with the $500 wall charger? I'm already set up in my garage with the 240V 50A power line, so I can add the wall charger. However, with the Tesla cars, I would just plug the mobile charging cable into the outlet. I havent seen much info about this.
