its not a little white lie its a big one, i think they call it insurance fraud
technically yes - and i would definitely NEVER EVER EVER do it but how they ever gonna know if someone was sooooo stupid enough to claim this??
i think as with most insurance companies, they have an investigation teams, to deal with fraud etc, don't know how they'd prove it, but they'll look for signs, like if the main driver has another car, or is insured on other insurance etc. i don't work in the industry so i'm only clutching at straws.
all i do know is insurance companies don't like to pay out, they do it because they have to, but if there is good option out, some will take it, i'd rather be up front and honest, than invalidate it, and risk insurers not paying out in the event of a big crash.
might save a couple of £100, but could cost you £1000's
premiums are there for a reason, your job is to find the best while still staying legal
