Asalam-u-alikum
As far my knowledge All Islamic and Other banks, All require Insurance, And Ullma already taken Insurance matter as haram,
Now if Islamic Bank says Insurance is Hilal, then it means Life insurance is also Hilal,
This is the main question, Further there are many other matter which all islamic bankers are doing wrong, For example it is in Islam that if any body owing loan do not pay back in time there is no charges, But if any customer late the installment they charge penality which is entirely against Islam.
So in the last i think that both modes are not correct, But i think in case of Islmaic banking if you take Car it's all responsibility of them.
It is only my thinking , your thinking can be different than me
