Parent named as main driver to save money
I am a parent looking for a car for my daughter. Is it not unethical in some way to call myself a main driver when I'm not just to save money? Will the insurance company not have a problem with it in the event of a claim?

A lot of people used to do that in the past and some even do it now so that their children can get cheaper car insurance as a new driver. However insurance companies know this practice now and this is referred to as car insurance fronting in the insurance industry. Not only is this illegal but it would invalidate any future claims should there be any.
New drivers' car insurance is really expensive and I understand that you want to help your daughter like any parent would but think about it for a moment - why does the car insurance go down when you say you are the main driver? It is because as the main driver, you have more driving experience and possibly have accumulated a lot of no claims discount over the years and because the main driver is supposed to be using the car more often, you are less of a risk to the insurer than your daughter.
I would advise you to let your daughter get car insurance under her own name even if it is expensive at first. This way she will be able to build her own no claims discount and believe me after one year, her car insurance will go down drastically.
