The problem is speed! In Switzerland we drive way faster than in Finland, especially in winter. 125-130 km/h is not uncommon to flow with the traffic, highway are everywhere. Consumption go crazy high (260-280 wh/km not uncommon). We also have mountains to climb (400-500 wh/km, even more) and regen is often limited downhill because the battery is often not warm enough. (Preheat battery is a nice stuff but we should be able to switch on ourselves on demand, especially if we know we have to drive only downhill after start)
