It’s pretty amazing.
I’ve driven through Switzerland multiple times. Funny story…12 years ago we were driving back when gps wasn’t as precise….we were heading to zermatt and noticed on gps the road just stopped on the directions.
I thought it was a glitch.
No…it really stopped…..at a train station where you ferry a car train through the mountains.
It ended up being awesome, but was a little perplexing at first.
