Set Speed to current speed when activating TACC rather than speed limit
When you activate TACC to set the crusing speed, currently the cruising speed is set to the current speed limit or to the current driving speed, whichever is greater (see manual, page 67).
This is not good, it would be better to set to the lower one.
Example. You are driving at 100 km/h on a road which allows 130 - and you WANT to stay at this speed of 100. Now you activate the TACC and the car accelerates to 130 and you have to scoll down the speed-wheel multiple times.
Even worse is this behaviou on german autobahns, because of the absence of speed limits on some routes. When you want to chill at 110, this is not possible without 9 times scrolling down after activating the TACC (from 150 to 110).
