Hearing is not a prerequisite to be able to drive or even to drive very well. Just like color blindness or even legs are not required to drive and drive well. It absolutely helps to be able to see in color to have a good hearing and to have all of your appendages functioning, but driving on the roads do not require these things. It requires an appropriate level of skill in relation to any handicap you may have. So what is your goal in proposing this? Is it to increase driver safety or is it to socialize the use of hearing aids outside of driving? Those are two totally different goals and I think conflating them is the wrong approach. Most of the problems we have with drivers is that we fail to require continuing education for driving. At least in the United States and I suspect many other countries driving is a skill that is taught early in life in the teenage years or early twenties. What is taught is the minimal acceptable level of driving. You get the rules of the road you have some hands-on experience with teacher that teaches you all of the most fundamental and basic skills needed. At that point you're handed a license and released into the world. This causes there to be people who have 60 years of driving experience but their experience is only in the most basic driving techniques. They have never learned advanced techniques for driving. If we want to improve driver skills there needs to be some sort of randomized continuing education that is required. This way people are guaranteed to learn advanced skills or at least have the opportunity to learn them.
