Yes, I have airbag drivers side only (assume badly fitting panel with nothing written on it passenger side is not an airbag).
Whilst I have experience with classics without PS most of what I drive these days either does or is my Sprite which has a large wheel and skinny tyres so I think my steering technique has been got a bit lazy. I've been concentrating the last week on steering actively with both hands, pushing not pulling and using my elbows and shoulders rather than my wrists. As a result I'm currently thinking that I don't need to upgrade.
