I don't think that will happen because there were already several accidents with test mules in the last years, not around the Ring.

A Porsche Panamera crashed on the Autobahn, driver died.

a Mercedes test driver was running maximum speed on the Autobahn when a mother swerved on his lane in her KIA, saw the Benz coming, overreacted and steered the car off the road, what killed the woman and her daughter......but this happens to me alot too. people just don't use their blinkers and rear view mirrors anymore, soon or later it will go wrong with me involved.

These ignorant people don't know how it feels like to slow down from doing 149 mph to 65 mph within seconds, just because they can't wait 2 seconds longer behind a truck to let me pass.

usually the Japs are calm drivers off-track, I saw them several times with GT-R prototypes and they were never speeding outside the track.

I honestly do believe the BMW test drivers did something wrong, young guns maybe.
