You should never treat flying like driving a car for the simple reason that if something goes wrong in an aeroplane you can't just stop by the side of the road whilst you work out what to do next.
I think his point was about the skill involved rather than the attitude.
Personally I find flying just like driving a car, similar motor skills and level of comfort. I use my aircraft to fly back and forward to work where I then get into another aircraft and fly for work. If you do something often enough it becomes second nature. This in no way undermines the requirement to ensure you are doing everything safely, just that it makes it much easier to do so.
Same with emergencies, I have had my share of emergencies and I am trained and current to deal with them and although the 'lay-by' is a bit more taxing to get into I have no issue with pulling over.
A lack of comfort is what keeps people convincing themselves that flying is hard.
