As I have said, I personally know someone that finds manual gearbox difficult and they hold a full licence for an automatic.
I thought you spoke for more than one single person? And if they have an automatic licence, they can't drive a manual at all.
So, presumably this person had problems when learning and gave up. With some perseverance, I am sure they would have been fine.
Someone opting to pass in an automatic to get an automatic licence is a world apart from claiming manuals are harder to drive, and many people struggle to use them while concentrating on driving.
And you still seem to have missed my post!
BTW, autos are not the next stop before hell. Anyone can choose to drive an automatic, and autos are convenient too. So, no problems there. I think the whole issue was the claim that someone might struggle to drive AND change gear at the same time. That sets alarm bells ringing about how alert someone might be to unexpected situations if even changing gear can cause problems.
Of course I've stalled, and crunched through the gears. That's not always down to lack of concentration. I've managed to slip off the clutch before, and tried to pull away with the handbrake on more than once. But, it hasn't caused me to panic and lose control.
