Your argument is the same as saying most people that live in cities don't actually need a car at all - just use public transport and perhaps hire a car for those odd occasions where you really need one.

I lived in a city for a decade without a car - and did exactly that - but when I had children - I found I needed both more certainty and more flexibility for my travel - so I got a car.

Don't underestimate those aspects - range impacts that flexibility ( not just range on a single journey, but cumulative range over a number of journeys without charging ).

Availability of charging points impacts both flexibility & certainty.

These are real concerns.

Range and charging are of course linked - if charging was easily available and very quick then range on one charge ceases to be much of an issue. If the range from a single charge is massive, then frequency of charge points is less of an issue.

So the good news is any improvement on either has a synergistic effect.
