I would caution that there’s a fair gap between “don’t need expansion joints” and “don’t have heat restrictions”. A few days a year of heat restrictions could be considered a reasonable engineering trade-off, if it manages costs
I’m not an expert by any means, but the engineer who makes the videos spent a good bit of time talking about the importance of building for the hottest days and how they do that. I don’t remember now if he talked about heat restrictions on speed, but the point was definitely about minimizing deformations to the track.
