We rented one of these fabulous cars for the 3-hour tour in advance of our trip. We were there right after they opened and got underway early. After instructions and bundling up with the blankets they gave us, we were off. The lack of windows didn't bother me as the driver--in fact, it was great to feel the waterfalls next to the road and to hear the bells on the goats close up--but my passenger got cold. Due to the early hour, there was still mostly shade on the road and of course it got colder as we ascended the mountain. By the time we got to the top, many buses had passed us and now all those passengers wanted to talk about the car. They took pictures, they marveled at our bravery to drive it, they rued their decision to get on a bus....We loved that little car, it performed just as we had been instructed, and we did all of the tour except for the farm visit. We had dawdled along the route and the road was getting busy. By the time we were heading back down, we passed about 15 other Twizys headed up the mountain. Indeed the lot was empty when we got back to eMobility. That made me even more pleased that we booked in advance, pre-paid, and got out their early. So many people kept walking by saying, "Let's do that." The Twizy traffic likely got quite dense. Lovely way to see and really experience the area near Geiranger. Loved it!
