Replays later showed Ricciardo’s hands being thrown around in the cockpit due to him still holding the steering wheel when he impacted the wall, with the Australian visibly in discomfort when he stepped out of the car.
Didn't Alonso break his hand last season in a similar way? I wonder if it's possible to have some kind of safety training or procedure to prevent this kind of injury.
It isn't strange to use your non-dominant hand for things, no. Maybe most people do lean toward using their dominant hand for everyday tasks, but I think it's a matter of habit for most things. "Non-dominant" doesn't mean "nearly useless".
I would say it is a bit strange for your friends to pay a lot of attention to which hand you use to unlock doors.
