Poland? 140km/h is the motorway speed limit. Admittedly there aren't that many Teslas here. But they are extremely popular in Germany and you see people drive them at silly speeds.
"Extremely popular in Germany" is a bit of a stretch, from googling around, there are only around 40k Teslas out of 48 million cars overall in Germany (which is about 0.08%).
Well, yes - I think what I really meant was that they are extremely popular[among electric cars]. Whenever I drive through Germany and stop at an autohof all tesla chargers are always occupied, and you see quite a lot of them on the roads just driving around. But you're right, 40k is nothing in such a big country.
Some German cars are driven at sillier speeds. I've been on the autobahn driving my Model S at well over 200 kph and been passed quite quickly by big German cars.
