Old Geico quote

Every time I've tried to get a quote with them it's more than I'm paying already
My problem is that I've got multiple vehicles and the insurance companies charge me 200 to 300 dollars liability on each car.
It adds up.
I imagine that's the same problem many people on here might have.
I know why they do it.
I know why the CAN do it.
But no one has ever been able to give me a reason for it that I think is valid.
Insure the driver for liability and not the vehicle, I say.
I can only drive one car at a time.
