I second @Robert M, @Stan Galat. No offense taken, and you are completely correct. The 1 is amazing, given you're not stuck behind motorists. And given the fact that it is on the bucket list of many, traffic tends to be quite slow.......especially in the late Spring through Autumn months. And it's just not the rented motorhomes, it's also those in their rental cars taking in the scenery.
Luckily, as mentioned above, there are roads north of the GG Bridge that are equally as beautiful. However, more and more are frequenting these roads as well. California's biggest problem is its congestion. Perhaps this summer, due to the pandemic, congestion along the coastal routes may ease a bit.
As long as I'm not stuck in traffic, I enjoy every road I'm on with the speedster. I know that's kinda a crappy reply, but it's true. The hum of the aircooled engine behind you, and the archaic technology of the car all lends itself to the experience, an experience that cannot be replicated within the confines of a modern car. Especially a push button modern car that does everything for you except steer.
