Have you driving in Puerto Rico? This is perfect for there. The distances are all in metric, but the speed limits are all in miles per hour.
No I have not driven in Puerto Rico but that is just another example why Tesla needs to decouple units of measurement at least for speed and distance as other car manufacturers do. It's also a problem for folks who commute for work at borders like the US/Canadian border. In my case my line of work uses distance in metric so I it's actually hard to convert on the fly imperial units watching the navigation distance count down..2 mi., 1 mi., 1/2 mi., 1/4 mi. 1/8 mi. 500ft 400 ft...and so on. I think yards are mixed in there somewhere..lol
