The steering wheel of old cars is often only the thickness of a finger and is usually made of smoothly wrought leather, mahogany wood or even Bakelite. All these are not good prerequisites for a good grip.
If you want to drive and park sportily and safely, you should get well-fitting driving gloves. This ensures better contact with the steering wheel than bare hands. It is important that the gloves fit like a second skin and offer full freedom of movement - so it is best to get driving gloves that have been made to your measurements.
