I guess most people in need of an utalitarian Family car for longer trips buy an ICE for cost vs. utility reasons, even if they consider a Zoe as the second car for daily commutes/shopping.

There are simply no affordable electric family cars in most European markets. By affordable I mean in the range of regular income families - most families don't have the money to spend twice the price just to have an electric car. Of course this is not true for heavily subsidized markets.
