Bit off topic I know, but I always drive with gloves on. The fingerless bicycle type, not the personal chauffeur / snooker referee type.Buy her some soft leather driving gloves
Car steering wheels and game console controllers always give me sweaty hand palms. Probably because of the concentration I give to the tasks at hand.
To afford me the extra grip and mostly not to transfer sweat to the steering wheel so my wife does not have to grip a sticky wheel (yuk!) when when she drives the car, I think it's best I carry on with wearing gloves.
I am not much into game consoles these days, so age took care of that one for me.
