Foldable exterior mirrors at 200

Hi Folks, has someone tried out there already ? Yesterday evening – Andi has stopped me for a long time – I had a nice time at 200 km/h (o.k., o.k. it was only 195) to fold in the outside pedestals (would have been able to bring another 1- 2 km/h more ). But they only entered in an angle of about 15° – then it was over. At about 160 km/h it went a bit further – but not completely. So – who can explain this to me ? saluti elkman now very excited
