I'll not see a massive take up in electric cars in my lifetime. I'd put money on it.
It's nice that Nissan will loan you an ICE car for your hols, but it's more the unexpected things that I'd be concerned about. What if your great uncle Geoff took a turn for the worse in Outer Mongolia, and your fun car was off the road? You're not going to be able to use the electric car to go and see him, and neither are Nissan likely to lend you a car at 10mins notice.
But yeah, for the small city commute where you have other transport always then they're great.
