To be precise it's 120 km/h in most, 130 km/h in some. At least in western/northern Europe (except Germany of course, with it's Authoban)

Yep, but it doesn't change the "base" point, which is, you cannot legally drive faster than 120/130/140 kmh (depending on the country) and certainly NOT 180 kmh in any European country BUT in Germany (and only on some - many - strerches of the Autobahn, in some other there is anyway a speed limit of 120/130/140 kmh):
