HopefortheBest - tell her to feck off then - 'tis one thing (imo) offering the odd lift from someone and another totally expecting someone to offer a lift.
If someone offers me a lift then yes I generally accept (have turned a few offers) but I never expect one - and (as far as I can reemmeber) have never asked for one.
The last lift I accepted was back from the local theatre where DS1's school choir (and 5 other choirs) had been performing.
I was torn between walking back (walked there) with him and getting a taxi. One of the other parents who lives past where we live offered me a lift - and as she was parked outside the theatre carpark (because they were late arriving) I accepted.
I got there quite early - if I'd driven I'd have parked in the carpark, and would have been sat there a long time trying to get out (one of my friends said she was sat waiting to get out for nearly 40 minutes ), and a taxi would have taken ages to get in as well because of the queues of cars and where the "pick-up" point was.
I can hand on heart though say that even when we had a car (and it's only been the last year that we've not had one) I never got a lift from DH anywhere - or got picked up from anywhere either
