No actually I don't think it is discrimination.

they have laid out these rules to minimize the amount of people an inexperienced driver has in the car. IF you have immediate access to another licensed driver (IE: your husband even though he works during the day) then you techincally don't NEED her to drive you with her being so inexperienced.

I mean I know you are close the situation and you see that your husband can't always leave work but these rules were put into place for extenuating circumstances like when someone has no one else available AT ALL at ANYTIME to drive them. I mean to "them" your hsuband is responsible for you... not your daughter.

Sorry

I would still try to call them and talk to them about your situation and see if you can be exempt but otherwise I don't think it's discrimination
