You can drive after a set time- I think it is 6 weeks but could be longer. Ditto with putting your socks and shoes on. I have forgotten the time, but you must use gadgets for a few weeks. yes, eventually you will be able to care for yourself.
At least getting this hip replaced will take some of the strain of the previously replaced hip.
You should have a chat with an occupational therapist, sooner rather than later about what you can and cannot do. You can also practice at home eg putting your socks and shoes on without bending down.
