I asked a few Tesla employees to stop saying 312 miles since it is more than U.S. Ideal range and nobody knows about EU NEDC cycle here in Japan. Still, some people think Model S can go 500km/312 miles and are shocked to experience fast decline of Ideal range while test drives. Yes the staff sets it to Ideal range for test drives. An uninformed guy believed in 312 miles (ordinary people can't read English forums) and purchased the car, disappointed, sold the car at a loss, wrote a crazy negative review about the car and the staff, now the review became very popular that everyone can find in top 10 of Google Search result for Tesla. So this is I believe Tesla's fault. How can I stop Tesla from false advertising? They even prominently display 312 miles at Tokyo and Osaka storefronts. Very bad for Japanese culture, which hates liars. They also show Superchargers on the web site, but since they are seriously behind schedule, they should reduce the amount of Supercharger content in Japan. Currently, I would say it's also false advertising. We have three in Tokyo a few miles apart, one in Yokohama out of the way for the most people, one in Osaka which Model S can't reach from Tokyo, and Kobe. We once had Kyoto, which is 300 miles from Tokyo, but they removed and no follow up after that. At least I can't say to my friends that Tesla is building Supercharger network, with confidence. I would have to say Tesla may or may not invest in Superchargers so don't count on them- if you're comfortable with CHAdeMO then buy it. I think Tesla is doing fine in other countries, which is good, but they are about to lose one market forever. They need to be honest. Please advise how I can help Tesla be honest in advertising and web site.
