@breizh One of these days you should try and automatic and see what you think.
Honestly, one of the most baffling experiences in my life is when I drove some British colleagues home at my first job and one of them told me they couldn't drive an automatic because it would confuse them.
The only thing that makes sense to me is when you learn on a manual, you have to think about what gear you should be in. Handing over that control to a machine might just break your brain somehow.
