I’ve flown the C152 but I won’t make any comments about why it appears the pilot didnt lower flaps. The reason why is because we dont really know what his circumstances were – maybe he didnt have enough time, maybe as suggested above he didnt want to affect the rate of descent etc Theres many reasons and I’d imagine coming down on a road is one of them situations where you’ve got to try and be abit flexible and make the most of what you’ve got.
