Any Mercedes, BMW or Audi. You can be driving on the autobahn here at 130 km/h (80 mph) and some German will blow past you like you were standing still.
It usually not the big cars, but the smaller ones. All you see is a blur and then they are fading into the horizon.
The bigger cars make people a lot braver over 100mph. And all those big German sedans will do 140 easy.
Quiet and stable.
On a wide open road driving alone, why not?
