Three cheers for Deathsled Dad!
My late 93 year old Uncle Larry was legally blind, but still had a license up until age 91 (with the same eye condition.) He had a trick to fool the DMV. How he read the eye chart was to go to the DMV the day before and (with his triple-thick monocular-glasses) memorize the 3 or 4 charts (it was a small DMV.) The next day, he'd recite them perfectly, while pretending to read them for the exam.
On family get-togethers, he always offered to drive us at night, because he said the outside looked the same to him as during daylight. We all laughed, but he could drive damn well.
Then, one year, he got tricked at the DMV because they made him read a new chart, after they suspected he was somehow cheating (his seeing eye dog might have given him away.) He lost his license then and there.
The next day, he of course was still driving his car. "I'm 91. What the hell are they going to do to me?" But, his son made him sell it.
So, Uncle Larry bought a golf cart and drove it, with his dog, everywhere including into the local supermarket to do his shopping. Yes, INTO the supermarket, down the aisles. A full-size gasoline golf cart. I'm not kidding.
"What's the difference between my cart and one of those old people scooters?" he'd ask anyone who tried to tell him he can't drive a golf cart inside the store.
As far as I know, he never got kicked out. He'd put his handicapped parking placard on the rearview mirror as a joke, while in the store. He liked to bang into someone's shopping cart and ask "Is this handicapped parking?"
He was a character. We miss him a lot. I'll bet he and Deathsled Dad would've had a crazy-fun Cannonball run together.
