You might be kind of glad they DON'T drive any faster! My dad was 85 and could only shuffle and his reflexes were slow, and we couldn't force him to give up his license, and the motor vehicle department only required a vision test. He finally put his car through the back of his garage when he couldn't get his foot on the brake, and my sister and I finally got his car keys away from him. Both ends of his car were dented and dinged. It's like he used it for a battering ram whenever he parked. Thank goodness he never hurt anyone. Sigh...
He and my Mom used to drive an RV from Wisconsin to Arizona in the winters, for about 10 years, and finally when my Dad was 77 he decided he couldn't do it any more.
Don't you think it's weird that people can retire, buy a huge RV, especially those popular huge 5th wheel trailers, and get behind the wheel after having never driven anything but a passenger car, and not need any kind of special license or test? It's crazy.
Okay, end rant.
