That is still a reasonable range to use
And no issue when used as a second car

It's almost as if people forget that ICE engine cars don't typically last beyond 200,000 miles.

My old Ford Focus was an economical write off, the engine was burning oil at 135,000 miles.  My old Peugeot had coolant leaks in the cylinder at 115,000 miles that could be temporarily fixed with "RadSeal", but led to oil slowly making its way into the coolant.  The Japanese marques might do better, certainly.  But I still doubt they'll outlive an EV with a stable, liquid cooled battery.

Truth most modern engines need new piston rings at about 100,000 miles
And head gasket failure is in most cases a consequence of failure in the cooling system

Both are easy to repair and parts are cheap, but takes about a day or two of service work what can be an issue and not many services do this kind of work today. They do just the easy repairs  ::)

But also there is plenty of ICE that fail to metallurgy fatigue at about 150,000-200,000
As they are engineered this way to make them cheaper while most owners do not use cars this long
ICE can be easily built to last 1,000,000 km but it does not make much economic sense as it makes it more expensive to manufacture and might slightly increase fuel consumption plus people do not like to ride in 20,30,... years old car

If on demand fast chargers are supposed to be the solution for everyone without a driveway that will require a significantly higher peak power delivery from the grid and the storage, that's a lot of extra power on a Friday afternoon, not sure if it will be cheaper. In fact I suspect it would be so expensive that fast charging would be done on appointment (with on demand fast charging possible with higher cost per kwh). Either way, less convenient than just extremely high density of roadside slow chargers.

It was a reply to comparison with conventional filling stations. Show chargers should be located at places where the cars would be parked anyway for other reasons than just charging.

But instead of fuel tanks you could have on-site BFO batteries which charge 24/7, and the cars take their charge primarily from this on-site storage.
