I guess you also feel it's dangerous adjusting the volume on the radio as that takes more effort than dripping.
As an ex roll your own, as I keep saying, I could roll and drive and not take my eyes off the road ahead and around me, as i instintivly knew where my tobacco was and could roll one handed, but to change the radio station I need to glance over as I cannot operate the control from memory.
When I was drip driving, it seemed to naturally fit into the flow, Ii never once felt as if I had 'missed something' or failed tomove when required to do so by the other stationary vehicles in front.
