One of the biggest advantages easily. I've seen my fair share of shitty 3rd party chargers and my co-worker also got so sick of dealing with broken chargers, after his lease was up, he went straight to Tesla too after I told him I drove over 600 miles without any issues. Charging at home is the ideal situation, but when you're on a long road trip, the last thing you want to deal with is pulling up to a charger and realizing it's fucking broken.
