Using Chrome, at Tesla Motors | Premium Electric Vehicles if I change the region on the bottom of the page to Canada (En) it isn't remembered and next session it goes back to US every time - highly annoying. I haven't disabled cookies or anything. Also somewhat related, I notice on the Model S page, the US version has a 'Charging Estimator' widget whereas for Canada it disappears. Probably because there's an electricity cost figure there which they don't want to deal with. But then if so, why not just have a value you can change? We can of course just use the US page, but who wants to deal with obsolete units like miles.
