The reason ESP can’t be turned off…

Hello together, I have so far not been able to understand many manufacturers, why they do not create a possibility to completely deactivate the ESP.

I thought the reason to protect the people was absurd, who is please so stupid and deactivated ESP without which he is aware what consequences it has? Well, after I have looked at the following video I have to give the manufacturer unfortunately right:http://bier tijd.com/mediaplayer/?itemid=30871
