Can only share my dated perspective. Given your interest in donating your body to science, I'd explore options with area medical colleges, hospitals for what is needed to effect your preferences. Also, cremation costs are coming down so you could also explore that option. Normally, those accepting your body for science incur ALL costs.
Unaware of your State regs, most provide statutory POD (payable on death) accounts, meaning on your death your child need only tender a copy of your death certificate to claim the then current balance.
Your daughter would NOT be legally responsible for your unpaid bills upon death (if titled in your name alone), but creditors would have a claim against your estate. Also, that does not mean creditors would NOT TRY to collect from your daughter so she needs to understand her rights.
As to the car, typically if your estate is small your daughter could petition the probate court to have your vehicle assigned to her upon your death. If of no significant value, she could sell as a beater or to vehicle salvage for metal content.
Must believe she is appreciative of your efforts to ease her pain, handling of your estate.
