I will arrive in Bangkok on July 22nd and drive to Hua Hin directly. Could any bro recommend some scenic spots along the way and in Hua Hin? Thank you in advance ?

I drove from Bangkok to Hua Hin last time, but I arrived in Bangkok in the early morning, so the road was empty along the way. It is worth noting that there are three routes from Suvarnabhumi International Airport to Hua Hin. It was my first time renting a car in Thailand, and I was not familiar with the road, so it took me more than 4 hours to get there. I suggest not choosing the route along the sea, because it is a rural road, and sometimes they occupy the road to set up stalls and then use road signs to block the road. This happens frequently, so you often have to deviate from the navigation route. Therefore, it is not recommended to take the route along the sea (river). The other two routes through the city are better and free of charge.
