Many deaf people drive safely, especially with some accomodations to their disability, as the article mentions.
I'd be more concerned about their ability to communicate effectively with customers.
please, can we reason above the jr high level?
Being physically capable of operating a vehicle doesn't qualify one to be a professional operator, any more than being able to swing a bat qualifies one for a profession in baseball.
Regarding the deaf individual's ability to communicate, it is really case by case basis. There are many Deaf people who are currently using hearing aids and cochlear implants to communicate with their customers.
Rush Limbaugh comes up in my mind, no matter how much he is able to use cochlear implant, he is Deaf without using it.
So if FReepers are making fun of Deaf people on this forum, or accusing them of not having an ability to do a mundane thing such as driving, that is quite childish to do so.
Odd enough, at the same time I do doubt that the same FReepers would forbid Rush Limbaugh from driving to his job at the radio station.
That's what my near deaf co-worker said.
