2-week road trip through Scotland

Hello, I feel drawn to the United Kingdom again. I was last in Scotland in 2023, but only briefly, and only on the fringes of the Highlands. In between, I had short weekend trips to Edinburgh and Glasgow. My plan is to rent a car again and then roughly drive along the coast through the country. Accommodations via AirBnB (but I always compare AirBnB, booking.com, and hotels.com). But at least once or twice I want my classic cottage. Look at the landscape, look at the cities, do some sightseeing, maybe jump into the sea, maybe go to a museum, etc. If you have another destination in the UK, or also Ireland in mind, we can talk about it. What's only important is that you have a driver's license. Unfortunately, I don't have one. You don't have to be afraid of driving on the left. Everyone has managed it easily so far, and besides, I'm a good passenger, I think, and I know my way around there quite well. We can surely discuss everything else.
