Vaping Weed While Driving

I was invited to spend a week with someone I had dated when I was in college. My love was not reciprocated back then. He was not out. His feelings were never spoken (unless he felt contempt or wanted to mock someone). He was pretty selfish most of the time. And full of himself.
Back then his greatest aspiration was to get high or buzzed. He drank Colt45 and toked weed which he would blow out the window through the tube from paper towels. His alternate state of consciousness was more important than sharing anything meaningful with another person (unless the other person were a dealer).
So, when I went to his home in Florida (some 45 years after I had first met him), he had a KiA with lots of beach sand in it. He never drove when he lived in New York. His driving is reckless; he exceeds the speed limit by 15 or 20 miles/hour, he slams on the break when the car in front of his slows down, and he vapes pot while driving. He claims that it's okay since it doesn't give a buzz. (No buzz? What up with that? Why bother?)
There were other things along the way that were annoyances such as a refusal to get off the road for a stretch or pee break (I have an active bladder and had no idea that anyone would be so obsessed with speeding to get to a destination).
I spent a good deal of the vacation on my own. That was actually a treat as I had certain food interests that my host didn't share. I was also relegated to sleeping on a pull-out sofa that had one very uncomfortable mattress. I wound up sleeping on it while it remained a sofa.
At the end of the trip, I thanked him for the vacation. I paid for half the gas and treated him to a few dinners (with other people whom I did not know). I sent him a gift card to the OLIVE GARDEN. I have only spoken to him once or twice since my return.
It's hard for me to believe that after 45 years I had refused to overlook this man's selfishness and need to be high all the time. I'm also sad that he never learned how to love someone else. Oh well.... his loss. One thing for sure, however, is that I will never vacation with him again!
