Pedantic: No, he was presented with a risk-reward trade off and he made a successful call. We don't know enough to properly judge if it was a correct call, it just worked in this instance.
Still. Let's say you're playing Blackjack and you're dealt a 19, while the dealer has an 8 showing. If you double down and wind up with 21, and the dealer ends up at 20, you may have made a winning decision--but that doesn't mean it was a smart decision, just lucky.
Not that someone suffering a pulmonary embolism is in a great situation to weigh their options very well. I think the ideal might be calling 911 to say "I'm going northbound on I-Whatever at exit 100, if an ambulance can catch up with me I'll have my hazard lights on and be laying on the horn; I'll pull over when I see the ambulance so you can save my ass. Either that or you can drag my unconscious body out when my car stops".
It's also a lot cheaper to drive yourself than call an ambulance, but someone with a Tesla is probably not very worried about that.
