I have to say that when we visit the local pubs on a sunny day (Cheshire is blessed with quite a few*, though my Calvanist ancestors would have said 'cursed' - erm, sorry, where was I? Oh, yes, Pubs! It's the men who show most interest! We must have offered a free ride round the car park a dozen times or more and it's always the men, generally young - midlife - who accept and come back with a big grin on their faces.It's a British thing. I find UK males in particular need a reason to take advantage of the assistance, and don't like to admit to needing or enjoying the advantages the electric motor provides. I think it's a protestant work ethic thing, combined with a machismo attitude.
Women and Europeans seem to spot the benefits straight away and don't suffer the guilt of electric assistance.
