Why shouldn't they?
It's not always the driver who's mobility is impaired either.
No one is saying they shouldn't, just that it's pointless using an outlier to justify your viewpoint.
Yes there are many mobility impaired people. For the majority of them an EV is great - one pedal driving. For those needing wheelchairs and who can drive, the car can be fairly easily adapted to hand control only. FOr those needing storage for their wheelchairs, cars exist such as the e-berlingo with its 170ish mile range.
If you are a wheelchair user who regularly needs to travel long distances, you are an exception, not the rule. And yes, there may not be an EV that fits your use case *yet*.
It does not follow however that we should abandon EVs because there are:-
those who need an affordable functional vehicle that will accommodate a wheelchair without having to dismantle it, and wish to make reasonably long journeys without stopping for 20 minutes every hundred miles or so.
I would argue that this group of people is very *very* small.
