Dogs love to ride in the car because they just want to be where ever it is we are going.
Have you ever noticed that they love to stick their heads out the window, but hate it when you blow in their face?
They think dogs have a sense of smell that is 1000 times more acute than ours. Man has five million receptors, dogs have 300 million to my understanding. So when the dog sticks his head out the window, maybe it’s like watching the country side flow past at 1000 mph but seeing every detail going back in time a good ways, like watching some of the best movies ever at once.

As a side note, my dog loves 140 mph trips down the highway. Really not as happy on exit ramps. lol
