I rent cars, pay for groceries, and basically do everything else with Bitcoin. I have to use card gateways like Bitwala for that, but it works for me perfectly. My debit card can be usually loaded with Bitcoin within 10-15 minutes (it is especially helpful as I live in 2 countries and travel a lot; bank transfers take much more time).
There are many companies now where you can get your salary paid in Bitcoin. In fact, it is so infinitely more convenient, I think that only the forces of mental inertia hold this approach from immediate universal adoption.
My credit card does all of that and they actually reward me for using them, so given the choice when paying for something I will choose a credit card 100% of the time.
