That's not how I read it. The summary was pretty specific... "The next day" isn't a summary of the trip, it's a summary of that day. That day, the car projected 32 miles. It delivered 51. It didn't "fall short" that day.
Notice how his red highlighted area encompasses the summary (which is in a different font-size) and the bullet-point-like annotations...yes, I guess if you read the infographic in that left-to-right fashion, you would make that connection...but if you read it in numerical order (as indicated by the numbered bullet points), you would not associate the two statements.
I'm reading that the same way he did. When I read it, it is very clear that "that day" refers to Jan 24th. The day in which it told him it would go 32 miles and went 51.
