Is Campagnolo EPS easier to shift with heavy gloves? It seems that it should be easier, with a clicking lever and thumb button.

I thought this was good design, either for a dead battery or a cut wire or a system crash. The rider can manually move the chain to a specific cog if the shifting fails.

Features and Tech page.
RIDE BACK HOME function
The uncoupling mechanism of the rear derailleur is useful if the battery runs out «on the road». If this happens, there is a procedure called RIDE BACK HOME that allows you to manually «uncouple» the rear derailleur to position it on the required sprocket.
Once you are «back home» remember to couple the rear derailleur back on and charge the battery.
