I had this thought recently too. I was wondering how a USPS vehicle being nearly silent could impact elderly who know the sound of the vehicle to know when mail has arrived. It could result in elderly making additional trips to the mailbox increasing their risk for injury in the event of bad weather. Or could they miss getting their medication because they do not think mail was delivered. Where I live mail is not always delivered on the same time even weekly. Without hearing the distinct sound of the mail truck barreling down the road I would probably have to check the mailbox more than once a day.
