From my experience of using an electric car, I do go slightly slower on the highway than when I was using a ICE.
Not because of range anxiety, the electric charging network is well developed in France so finding a place to charge has never been an issue so far.
No, it's because when you get an electric car you start being way more conscious about how much energy you are using and the energy usage difference between 130km/h and 110km/h is quite significant for not a big difference in time.
