The benefit of a fossil over an EV is all about charging, where chargers are hidden in narrow parking spaces or require you to climb super high curbs in your wheelchair, but petrol pumps are usually far easier to use. Set that off against those who can charge at home with no need to visit a petrol station ever again and you see a split picture on EVs for disabled people.
Effectively, once the providers of chargers stop discriminating against the disabled, EVs can work.
There’s also the problem of finding large enough EVs on the scheme, although with the arrival of EV vans I hope this will be addressed.
So, we’re not there yet for EVs only, but that day will come.
