Re: 350kW!!,
That would only be an issue if you tended to drain the battery down to near zero before charging.
Typically, if you trickle-charge every night, then an average daily commute would still leave you with 80%+ charge. Note, this is typical/average, i.e. urban dwellers, yes there are exceptions for people who live in remote areas, or have high usage (e.g. delivery drivers, etc.).
Therefore it is unlikely you'd have to charge before dashing off to some urgent pickup for a typical person.
And if you were out of charge for some reason, then there's always walking/biking (if not too far) or friends/neighbours/relatives/public transport/taxis if it truly is an 'emergency'.
