Yes, 14 days is reasonable for most patients.
I advise my lower body lift patients not to drive until they are safely able to control a vehicle. This means not being on strong pain killers and being physically capable. You need to be able to safely get in and out of the vehicle, use a seat-beat, perform mirror and shoulder checks. For example, if you have a big car that is high off the ground this mean may you have to wait a bit longer.
You need to be sensible and start off driving short distances, gradually working up to normal driving.
