European driving is much easier and quicker than the UK, unless you are visiting big major cities.
I see you are heading to Switzerland........unless you have something specific planned for France, skip it, you can get to Geneva in one day quite easily. Once in Switerzland you really do have access to some of the best roads in world!!!! Its honestly like driving through some kind of endless car advert, no traffic, beautiful roads, amazing scenery, pretty much everything that is the opposite of driving in the UK!
Regarding Spotify, been to France a few times now in our Tesla, no issues with connectivity - Sat Nav does take 10 minutes to catch up once you exist the ferry/train, but thanks to Brexit, extra checks means you will be sitting in a traffic jam at passport control for about 30-45 minutes anyways
