Self-driving cars still need a way to pass that specific mountain range. Right now there is the old rail tunnel, the road tunnel and the mountain pass. The latter usually closes in autumn as do many others in the Alps. The road tunnel has a length of 16.9 km and two lanes. All of this creates a huge bottleneck. So unless someone invents a flying car, tunnels will still need to be built in regions like this.
